Palm Vx greyscale image problem
I've created a greyscale bitmap family for use in an application, but my Palm Vx always resorts to using black and white -- it won't display grey. However, I know that it's capable of grey. If I delete the 2-bit image from the family, the Vx just displays the 4-bit image in very blocky black and white. I'm lost. Any suggestions?

please wait dialog not working
hi,
im trying to implement the please wait dialog in my app. This is what im
doing with my code, here are two snippets of my code, I call
FrmPopupForm(PleaseWaitForm) and that goes to the PleaseWaitForm Event
Handler. The PleaseWaitForm waits for a nilEvent, when it occurs I call
FrmReturnToForm(0). Then i want it to keep processing and go to
ConfigName(UnsuccessfulAlert).
Now it goes through with no errors, but the Please Wait From never gets
displayed. I don't know how to do it???
Thanks for any help...
James
case ctlSelectEvent:
{
switch (eventP->data.ctlSelect.controlID)
{
case ConfigOKButton:
FrmPopupForm(PleaseWaitForm);
ConfigName(UnsuccessfulAlert);
FrmReturnToForm(RetrieveSendForm);
handled = true;
break;
static Boolean PleaseWaitFormHandleEvent(EventPtr eventP)
{
Boolean handled = true;
FormType*frmP = FrmGetActiveForm();
switch (eventP->eType)
{
case frmOpenEvent:
frmP = FrmGetActiveForm();
FrmDrawForm ( frmP);
handled = true;
break;
case nilEvent:
FrmReturnToForm(0);
handled = true;
break;
default:
break;
}
return handled;
}
Thanks

.bmp causing a SysFatalAlert
I placed a bitmap on a form using constructor, and im getting this SysFatalAlert message when i load the form: SysFatalAlert with the message: "MemoryMgr.c" Line: 4365, NULL HANDLE I have the image in a bitmap family and i have two brances a color and a gray. What is causing this, i debugged the program and couldn't make much sense out of what the debugger was running into: AppEventLoop 0x10078F76( FrmDispatchEvent ) 0x100753B6( PrvSendEventToForm ) PleaseWaitFormHandleEvent 0x10075DE2( FrmDrawForm ) 0x10020B1A( MemHandleLock ) 0x10021B00( PrvHandleCheck ) 0x10021B00( PrvHandleCheck ) 0x1001E6EE( ErrDisplayFileLineMsg ) the only functionality of this form is too display itself and wait while a data transfer takes place, when the transfer is done it closes up. The form has two labels on it and a bitmap, and it is setup as modal. thanks for any input. jim -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
Flash a form then close it on a stylus tap
I checked the KB and i also did a search on this forum, but couldn't come up with anything pertaining to this subject. When my app starts directly from the stylus tap on the icon i want to show a form that displays a bitmap and some text. Then i want the user to tap the screen and be able to move on into the program. Is allowing the user to be in control of the movement of the program a good idea or should i have a timer of some sort that would time out five seconds and then move on into the program? How would i implement this into my app, i currently just have it so you manually have to go to the menu and select the next form to continue the program. I thought this would be a good idea when i noticed this feature being used by the Palm OS during the calibration for the digitizer when the palm is reset. It displays a form and then asks the user to tap the screen anywhere with the stylus to move on. Thanks for any help, i appreciate it, and I also find this forum extremely helpful and if i were to give any advice to a newbie i would say take the time and read every message that is posted because that information will seep into your brain and stick like a sponge, the way you want it t... jimmy -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
SysFatalAlert
I building an app and i tested it out on the emulator. I first tested it on the m505 w/ color and 4.0 OS emulator and it ran fine with no problems. I then tested it on the PalmVx w/ 3.5 OS and it crashed and gave me this error message: -[name of application] v1.0 called SysFatalAlert with the message: "Form.c, Line: 1728, Object not in form". What does this mean? I don't understand why it won't work on one but not the other, is it because of the different operating systems? Thanks in advance for any help. jim -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
Handling Menu Events....
Im puzzled by this code found in many examples i have been looking at: field = FrmGetObjectPtr (form, FrmGetObjectIndex(form, MainNameField)); This particular example comes from a simple HelloWorld app. Whats confusing me is the MainNameField portion. In the HelloWorld App there is only one field that gets handled. Im doing an app where there is many. I have this same code in my app but it isn't working because of this expression. If someone could give me some help it would be greatly appreciated What im basically asking is can i have a function called MainMenuHandleEvent that works with the same with all the different forms i have in my app, and if i can how do I do it???
