Development tool based on VB
I have made an application in VB 6.0 and EVB 3.0 for PC and Pocket PC 2002/2003 respectively.Now i want my application to run on Palm OS devices too. For this i have studied the tutorial which comes with the CodeWarrior and i have realized that it is based on C++. Is there any development tool based on VB which will allow me to make my application for Palm OS devices. I have heard about AppForge and NSBASIC but i am confused as to which i should purchase. I don't want to make a wrong decision. My application requires a strong user interface and alot of mathematical calculations. There is also some database handling involved in it. (Both local and remote i-e on the internet) I need advice on this. I hope u will all help me in making a correct choice.

auto reset
Hi, all. In my application, when I create a new database, it returns to the list view form as expected. I can't read it right away, and the device reset automatically. However, when I install the application again (using shortcut 2), I can read the database. What are the possible reasons? _ Linguaphone : Learning English?

RE: Resizing resources and soring multidimentional arrays
Thanks! I can't believed I missed that. I opened the database in read-only mode! Now I have a problem with what lies within that resource. The resource begins with a structure, lets say 'ResHeaderType'. Following this structure is an array of 'ItemType' (of wich can have a varying # of entries), followed by a another array of say 'TileType' (of wich again can have a varying # of entries). ResHeaderType has values that state how many ItemTypes and TileTypes, lets say 'NumOfItems' and 'NumOfTiles'. Rptr is a pointer to the start of the resource. How do I obtain pointers to the first ItemType and the first TileType? Would the following work? ItemType *Iptr = (ItemType*)(Rptr + sizeof(ResHeaderType)); TileType *Tptr = (TileType*)(Rptr + sizeof(ResHeaderType) + (sizeof(ItemType) * NumOfItems)); Would Iptr and Tptr point to the data I want? When I tried to do that, I seem to get scrambled data. I had no trouble writing to them by using sizeof(ResHeaderType) as the offset for the ItemTypes and (sizeof(ResHeaderType) + (sizeof(ItemType) * NumOfItems) as the offset for the TileTypes. >>I am trying to use the fuction 'DmResizeResource', and it keeps on >>failing.

Re: LIST Object and Setting font
I could call this function in my callback, but I'm worried about the perf hit I do this. Shouldn't be a problem. I'll let everyone know how LstGlueSetFont works. That should work fine too, but if your font has a height that is different than the stdFont (or whatever font you assign to the list when you define the resource), you might run into problems. You might need to call LstSetHeight plus some housekeeping (list erase, list redraw, erase the border rectangle, etc.).

Re: LIST Object and Setting font
I'll try the LstGlueSetFont, currently I do call the WinDrawChars function within my callback, for some reason it doesn't seem to be using the current font. At least, during form load, I do call FntSetFont to the custom font that I want to use, I've hook my FntSetFont wrapper to ensure that it's not being called with a normal font ID, I've found no place in my code that calls FntSetFont with the (stdFont), but I do see my call to this API with a custom font. Unfortunately when I call FntGetFont from the WinDrawChars function (my wrapper), the font is stdFont and not my custom font. That leads me to believe that something - somewhere outside of my code is calling FntSetFont. I could call this function in my callback, but I'm worried about the perf hit I do this. Any ideas?

WinScreenMode bug on Zire71/Tungsten E
Switching screen depth on my Zire71/Tungsten E device (probably happens on T1 and T2 aswell) causes a visual artifact. The display 'hickups' and a black rectangle with varying height and the width of the entire screen is displayed momentarily. Seems to me that this is the result of the DMA Controller stops providing the LCD Controller with frame data in the middle of a frame, resulting in that zeros instead of frame data are being sent out to the LCD Controller pins for the remainder of that frame. Do you others see this aswell on your devices? Perhaps someone from palmOne can comment on whether there is something one can do to avoid this behaviour? This happens when switching from one screen depth to another, i.e. from 8 bit to 16 bit and vice versa. (Trying to set the screen depth to the current value is probably ignored by WinScreenMode ) Below is some code if someone would like to test this. TIA, Jonatan Uint32 width, height, depth; Boolean enableColor=true; width = 160; height =160; depth = 16; // Set screen depth to 16 bit error = WinScreenMode ( winScreenModeSet, &width, &height, &depth, &enableColor); -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
RE: new hi-res bitmap not being used
The only suggestion I can make is that you ensure the high-res bitmap is exactly double the height and double the width of the low-res one. You don't need to use WinSetCoordinateSystem, since the OS will automatically choose the best bitmap that it is capable of displaying. So what exactly happens at this point? Does the low-res version still show up, or nothing at all?

Tools talk at developer conference
Hi All, We are going to be releasing some of our tools at the PalmSource developer's conference and I'll be doing a presentation on them. I think that many of you will find the tools really useful so please come to the talk. The talk is at 10:00 pm on Wednesday right after the certification exam and is titled, "Tools for Removing Roadblocks". I've only got 30 minutes and there is a lot to cover so I will end up primarily touching on the high points but it should give you an idea how to get going. Here is what I'll be talking about: 1. How to integrate PocketPurchase into an application. We have a new single-call interface that makes this easy. This is the only item that requires use of our service. 2. Creating an installer with our free Windows installer builder. The installer builder can generate separate EXEs for each web store automatically. It will install the PocketPurchase components automatically if it detects that the app is PocketPurchase enabled. It can install conduits and Palm Desktop shortcuts. It can also do some cool things like merge optional resources into your main PRC. Great for supporting multiple screen resolutions. 3. Our desktop Palm Data library. This library implements pretty much all of the Palm OS Data Manager and Memory Manager calls, plus a few more useful functions like TimGetSeconds. Using it, you can access PDB/PRC files on the desktop just as you would on the handheld, making it possible to share code between your handheld app and conduit. This library allows us to share code between our handheld app, desktop conduit and Linux back-end server. 4. PNO Glue Builder. Works as either a standalone tool for use with 'make' or as a CodeWarrior plug-in. It creates glue files to dramatically simplify using PNOs from the PACE layer. Using this tool, it took less than 15 minutes to add PNOs to WordSmith to do document compression and decompression. 5. Our Palm OS Language plug-in technology. A number of developers are using this as an easy way to create foreign language overlays. If you also use our installer, the installer will sanity check the overlays and can actually merge the foreign language overlay into the primary PRC file. 6. HotSyncDLLs auto-glue library. Why ship Palm DLLs with your app when the user already has them installed? Link with this library instead and your app will automatically link to the existing DLLs. This has the added advantage that your app can still load if none of the DLLs are present and do something appropriate. The installer, PNO Glue Builder and our language technology is already available online at http://pocketpurchase.com/tools so feel free to have a look now if you like. See you at the conference.

You must allocate some memory, say enough for 4 blocks, and then make
bufOrigin and bufCurrent both point to the beginning of that memory.
Then make bufPastEnd point to the address that is one byte beyond the
last bytes allocated. See how bufPastEnd is used in my callback to
detect wrap-around. Then, each time the callback is called, it will
advance bufCurrent by one block. As part of the nilEvent processing,
you watch for changes in bufCurrent and process the filled buffers
accorinding. Make sure to allow for the possibility that several
buffers may have been filled when you handle the nilEvent.

Indexed and direct color
I went to some trouble to convert an image from direct color to indexed so that I could flash all the colors in an image by just changing the palette entries. Works great in the emulator. However, on a real Palm Zire 71 device the speed at which the flashing takes place depends on how many pixels in the image have that color. This would imply that the palette or color table in these devices is fake -- the OS is actually writing individual pixels to mimic the operation of a palette. Can anyone confirm this? Is there information out there about the actual graphics hardware in various Palm devices (i.e., do any have hardware palette DACs??).

There are too many problems associated with time-based solutions, either the user resetting their clock, performing a hard reset, or the programmer installing an orphan (but hotsync'ed) db to counteract this, blah blah. Simply turn off a feature that makes your app valuable (but that doesn't interrupt the ability of people to use the app and figure out if it's worth $$ or not.) For a game, this would be removing the ability to save high scores, removing network play, removing bonus levels, etc, etc. For a media-creation tool, removing the ability to permanently save your creation would work fine, or removing the ability to save in any format other than your proprietary one. It really depends on what your app does. Rather than create separate trial/full versions of the app, I also chose to implement a registration key method. The user receives a registration key when they buy the product, and then they can enter it on an input screen in the app. If the reg-key is valid, the program unlocks the closed features and thereafter functions normally.

emulator message "Windows can't be under forms because they can't be
redrawn". I understand what the message is telling me and why I am getting
it. So is there an "accepted" way to display the type of wait dialog that I
am displaying? The function I use is as follows:
void PopUpWindowV20(int bmp, int toggle,int left,int top,int width,int
height)
{
RectangleType rect;
Worderr;
Err error;
WinHandle formWin;
static Handle resH;
static BitmapPtrresP;
static WinHandlewin;
if(toggle == ON){
RctSetRectangle(&rect,left,top,width,height);
resH = DmGetResource( bitmapRsc, bmp);
ErrFatalDisplayIf( !resH, "Missing bitmap" );
resP = (BitmapPtr)MemHandleLock(resH);
win=WinCreateWindow(&rect,dialogFrame,true,true,&err);
if(!err){
//WinEnableWindow(win);
WinSetActiveWindow(win);
WinSetDrawWindow(win);
WinDrawWindowFrame();
WinDrawBitmap (resP, 0,0);
}
}
if(toggle == OFF){
WinDeleteWindow(win,true);
error=MemHandleUnlock(resH);
//if(error) FrmCustomAlert(CustomAlert,"Unlock problem in
PopUpWindow.",NULL,NULL);
formWin=FrmGetWindowHandle(FrmGetActiveForm());
//WinEnableWindow(formWin);
WinSetActiveWindow(formWin);
FrmUpdateForm(FrmGetActiveFormID(),frmRedrawUpdateCode);
}
}
Thanks,
Phil Lachmann

RE: Transferring Resources from Mac to Windows

Re: about stack size
I create my project using PNO option,I have found a way to change 68K's stack size,please see the attachment. I can set the "Minimum Stack Size",and Can I set the max stack size?If not,what is the max stack size? But I don't set the stack size on PNO part,I don't find any option.Please help me,and thanks. There is no stack size setting for PNOs. If you want your own stack, you need to allocate memory for it and change the R13 register using inline assembly to point to the top of this stack, being sure to restore the original R13 value before returning to the OS. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

How to display list of available network connections?
Hi all, What I want to do is allow user to switch between network connections. Network connection should be taken from preferences/network and should be displayed in list. I played around with NetLibConfigList and NetLibIFSettingsGet but unsuccess. The staff given by NetLibConfigList containt some internal strings with the "NetPanel" string at the end ... nothing more. I created programatically the network connection too. NetLibConfigList showed created connection but in the preferences/network was not shown. Any ideas? Thanks. === Visicom s.r.o.

Porting a large C++ program
Hi I'm looking into porting a large C++ library to the PalmOS (v3.5 and higher). The library is certain to become bigger than 64K. Exceptions and RTTI are not used, so that should not be a problem. The library uses global const data only. Virtual methods are used too. The library will then be linked to a PalmOS specific UI level program. This will probably be written in the c++-as-a-better-c language. I intend to use the PRC-tools. >From Googling the web and then reading the found articles, it appears that I have now two options: 1) create a GLib shared library. 2) create a mulit-segment application. It's clear to me what I should to to get both cases to work. What I cannot figure out is what the best approach of the two is. Both methods appear to have their problems, but I find very hard to figure out whether one of these problems is a showstopper for what I want. So if you people could shed some light on this or point me to a website that has the state of the art and is unknown to Google, that would be very kind. -- Sander van der Wal -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

Thank you! So, it is a fault in the T1 and the T2 after all! I wonder if there is any use is contacting Palm? I just went through a 6-month ordeal with Dell and the Axim X5 for a similar issue. They eventually released a patch to the Axim sound drivers, but only after I had recruited an army of complainers and found every other vendor of sound-input software for the Pocket PC and got them to confirm my complaint to Dell. I guess it would be nice if someone else could independently write some sound input software and verify that these Palm devices have a small but definite probability of hanging on SndStreamDelete() when the sound stream is "input".
