[Mono-winforms-list] MS Access DataBase and Winforms on MONO Linux
Hi All, Please any one help because I am stuck with this problem for some time! I have a application that is developed in .net 2.0 vs2005, and uses a access data base. But now this application shold work on linux (openSuSE). I tried it to start it with mono on openSuSE and the application runs untill there is no connection to database. The moment when the app needs any data from the database, the app crashes. I was reading and surfing around and I found that the GNOME.org has a library for access data base connection. I am installing it but still the same error. Please suggest, help if any.

[Mono-winforms-list] WinForms + WebKit + Mac OS X
Hi, I'm trying to use WebKit in a C# WinForms application running on Mac OS X and I have problems. Currently, I'm able to put WebKit control on System.Windows.Forms.Form instance, but it has rendering problems: the WebKit is overdrawn by the form background. It might have other event-related issues--not sure currently. Other approach was to create a native Carbon window using HIWindowCreate and put WebKit there. This works for WebKit, but not for WinForms controls: e.g., a Button added to such native window is painted, but doesn't respond to events (click, etc.) I _need_ both WinForms controls and WebKit[1] in one window. What I'm missing and what are the odds that this could be accomplished? More related details: The WinForms application is a sample with the only bare Form generated in Visual Studio. I'm using WebInitForCarbon() + HIWebViewCreate() to get a raw HIView pointer. I'm using Monobjc to wrap the native handle into WebView class and load a simple request--this part works w/o a problem. Any help and suggestions are very much appreciated. :) -- Cheers, Alex [1] Preferrably, but any other decent browser engine (like Gecko) will do the trick. ___ Mono-winforms-list maillist - Mono-winforms-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-winforms-list
[Mono-winforms-list] OSX TextBox accepts no input?
I'm kind of baffled by this. I can create a Form object and add a TextBox
object to it. I can give the TextBox focus and get a cursor. Nothing I type
while the TextBox has focus shows up. gmcs and mono both report version 1.9.
Code follows:
using System.Windows.Forms;
using System.Drawing;
public class MyC : Form
{
public MyC()
{
Text = "Simple";
Size = new Size(250, 200);
TextBox tb = new TextBox();
tb.Parent = this;
tb.Location = new Point(5,5);
tb.Size = new Size(200,180);
tb.Multiline = true;
tb.ScrollBars = ScrollBars.Vertical;
tb.AcceptsReturn = true;
tb.AcceptsTab = true;
tb.WordWrap = false;
CenterToScreen();
}
static public void Main()
{
Application.Run(new MyC());
}
}
I'm compiling thusly:
gmcs -r:System.Windows.Forms.dll -r:System.Drawing.dll MyC.cs
If there's something wrong with my code, I can't find it. Is this just a
limitation of mono on OS X?

Re: [Mono-winforms-list] OSX TextBox accepts no input?
You need to add "this.Controls.Add(tb);" towards the end of your constructor.

It's hard to say without seeing the code. Winforms does not depend, directly, on libgdiplus, System.Drawing does. *_linux functions are used in limited cases (like some OS specific stuff to generalize creating a graphic instance). At the end both Mono's System.Drawing and Winforms* needs to be able to execute under Windows. * Mono's Winforms also needs to be able to execute on top on MS S.D. > I'm doing the extra text metrics by adding methods in the > TextBoxTextRenderer class, which seemed to be the best place to do that. > For the Windows side of things, I'm having it make calls to gdi, which > provides some better metrics than gdi+, although not quite everything > I'd like.

On each other ? Really ? because I don't see why libgdiplus would depend on winforms changes (unless you meant S.D versus Winforms). Generally you should plan to merge the libgdiplus changes first, then System.Drawing and finally Winforms. Of course it's quite possible that it will require more than a single iteration. > I know I'll need to have all the current unit tests passing with new > code, and quite possibly some new tests. Yep, new features will need new tests. There are also a lot of open bugs (most with test cases) about string drawing/measuring that should be helpful. > Also, I m

[Mono-winforms-list] Problem with accessiblename property
Hi, I have a c# winforms application developed with VS2008. It runs merrily on a Suse Linux VM until the code tries to use the .AccessibleName property of a Label control. It then crashes. The same code runs OK back on the Windows development box which is referencing the Mono.Data and Mono.Data.tds dll's. Using MessageBox debugging I have ascertained that the code does not error when setting .AccessibleName to a value. However when checking for that value later in the code in the .AccessibleName attribute it isn't there. The same is also true about the AccessibleDescription property. I am an enthusiastic newbie to Mono and I am impressed with performance of the .Net c# running on Linux. Any comments or pointers would be most appreciated. regards Aardsoft -- View this message in context: http://www.nabble.com/Problem-with-accessiblename-property-tp21777910p21777910.html Sent from the Mono - WinForms mailing list archive at Nabble.com. ___ Mono-winforms-list maillist - Mono-winforms-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-winforms-list

I only had a quick look last week, but will look at it more carefully soon. A quick comment: it needs a ChangeLog ;-) > Should I create a bug in the tracker to help track the work on complex > script support? Yes, that would be useful - which brings me to a "long term" comment: libgdiplus can't switch to pango output until it becomes a superset of the features that it currently (custom text renderer) support - i.e. complex script support is awesome but not enough as many people depends on other features not yet available in the pango renderer. > Thanks, > Jonathan Anderson > > Jonathan Anderson wrote: > > I mentioned earlier that I was doing work to get pango support working > > properly in libgdiplus.

[Mono-winforms-list] Missing Text in WinForms Applications
First, I would like to thank all those who have put a tremendous amount of effort into getting mono running on other platforms. I have been aware of the mono project for years, but have never had a need for it until now. I am trying to run some basic WinForms applications using mono on Fedora 10. Thus, I installed mono 1.9.1. Everywhere there is text on the applications, whether the menu, buttons, checkbox controls, or anything else, my text has been redacted. In other words, there is no text there, just a black hole. Now, I have been out of the Unix / Linux loop for years now, and have not been very familiar with the current state of affairs. I am sure this problem I am having is a simple configuration issue, and I have tried looking about, but have not been able to find an answer. Anyone who can help me with this, I would greatly appreciate it. -- View this message in context: http://www.nabble.com/Missing-Text-in-WinForms-Applications-tp22032464p22032464.html Sent from the Mono - WinForms mailing list archive at Nabble.com. ___ Mono-winforms-list maillist - Mono-winforms-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-winforms-list
