I hate to have to ask you for somemore help, but I can't see to find an answer to what I thought would be a simple question.
How can you set the focus to an application? I think this might be a problem with my code. I think I need to set the focus back to Autocad in the event handler portion.
Thanks again.

Nevermind. It doesn't seem to work that way. Back to the drawing board. I found a way on this website.

Hello
Sorry I saw your post late. Here is the way -if you still want it-.
First, you can't do that using C# alone. you have to make some Windows API unmanaged functions. The functions import code is:
[DllImport("User32.dll", CharSet=CharSet.Auto)]
private static extern bool SetForegroundWindow(IntPtr hWnd);
Now this loop will go through all top-level windows, check their title, then activate the one that has "Autocad" word on it:
foreach(Process P in Process.GetProcesses())
{
if (P.MainWindowTitle.Length > 0 && P.MainWindowTitle.IndexOf("Autocad") != -1)
SetForegroundWindow(P.MainWindowHandle);
}
One flow is that all windows that has "Autocad" word on it will be activated sequentily. If you know more word in a single phrase -ie. as a sentence- this should narrow this error margin.

Thank you for the code. I think I need to submit it to the Autocad people (they have a network of developers that help others) because I think I have gotten as far as I can with just your great C# help. I think it is an Autocad thing now, and if you don't use it (code for it, like it looks like you don't) then I don't think one would know how to fix it so that it will work.
Thanks again for your patience, and help. It's greatly appreciated (hope your not sick of reading this type of stuff, because it is sincere). If you want I will post the code that does work, sometimes people just like to see what was wrong. Who knows.

Hello
Thank you for your kind complements. I'm always happy to help you anytime.
What I got from your post is that your code didn't work out!! Why?? I though it did display that orbit thing, and all your problem was with the timer?? Sorry I don't have knowledge of Autocad, but I hope I helped you enough with the C# part!!
Anyway, if you still want to work out your code, just tell me what a non-autocad problem -if any- would be. If you found a working code, I'd be happy to see it.
Anyway, I wish you luck.
Regards

I have a Winform with a button. The Button Text is set to &RUN. When I open the application the Button does not Display RUN until I hit the Alt key. Is there a way to make this underlined when I open the app.
Thanks

That is a windows setting, it can't be changed in you app without effecting the entire system.

Hello
There is a workaround the problem, even though it will be a diviation of the standards of windows programming - for example you can show your mainmenu at the bottom of your form, but is that right?
Anyway.. Handle the Paint event of your button and use e.Graphics object in the handler to draw the line at the appropriate coordinates.
Regards

Hi,
I am trying to change my form background image onClick from a button. I have this so far but it doesn't seem to be working and I can't workout how to do it!
this.BackgroundImage = (System.Drawing.Image.FromFile("theme\red.png"));
Can anyone point me in the correct direction?
Many Thanks,
Al

The \ character is an escape key; the string will take \r to mean a return character code. To specify a string with an actual \, you need to either use a double-slash or the @ symbol:
this.BackgroundImage = Image.FromFile("theme\\red.png");
or
this.BackgroundImage = Image.FromFile(@"theme\red.png");

Just to let you know, here is a list of escape sequences you might want to use/avoid.
regards

Is there a way for me to convert my existing C# files to have .designer.cs files? I am working on a very large project and this would be a very useful change to our project. Are there any articles explaining how to do this by hand if there is no automatic converter?
|

I've never seen one myself, unfortunately. You *could* write something that would do this: basically create a new file on disk in the same folder as the original file, scan that file for the Dispose and InitializeComponent methods, then move them to the designer file. Shouldn't be too difficult.

I'm drawing text using TextOut and when I required text to be vertical I needed to use LogFont to set the orientation. Hovever when texting it on the origional function I made everytime it draws it, its slightly different and reall messed up. Like it will be much bigger and italic and striked outdespite the LOGFONT object saying otherwise.
Here's an image of what it looks like: http://www.draders.com/images/CreateFontIndirect.jpg[^]
The function is:
public static void DrawString(Graphics g, string s, Font Font, Color ForeColour, int x, int y) {<br />
IntPtr hdc = g.GetHdc();<br />
LOGFONT LF = new LOGFONT();<br />
Font.ToLogFont(LF);<br />
<br />
IntPtr fntNew = CreateFontIndirect(ref LF);<br />
IntPtr fntOld = SelectObject(hdc, fntNew);<br />
<br />
SetTextColor(hdc, RGB(ForeColour));<br />
SetBkMode(hdc, BackgroundMode.TRANSPARENT);<br />
TextOut(hdc, x, y, s, System.Text.Encoding.Default.GetByteCount(s));<br />
SelectObject(hdc, fntOld);<br />
DeleteObject(fntNew);<br />
g.ReleaseHdc(hdc);<br />
}
The logfont produced (using the default forms font) is:
LOGFONT
lfHeight: -11
lfWidth: 0
lfEscapement: 0
lfOrientation: 0
lfWeight: FW_NORMAL
lfItalic: 0
lfUnderline: 0
lfStrikeOut: 0
lfCharSet: SHIFTJIS_CHARSET
lfOutPrecision: OUT_DEFAULT_PRECIS
lfClipPrecision: CLIP_DEFAULT_PRECIS
lfQuality: DEFAULT_QUALITY
lfPitchAndFamily: FF_DONTCARE
lfFaceName: Microsoft Sans Serif
I noticed the height was negative and all examples I've seen set it to a positive value, so I tried setting it to 11 before calling CreateFontIndirect and that caused it to not draw at all.
The LOGFONT object and CreateFontIndirect function I used are:
[DllImport("gdi32")]<br />
internal static extern IntPtr CreateFontIndirect([In, MarshalAs(UnmanagedType.LPStruct)] ref LOGFONT lplf);<br />
<br />
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]<br />
internal class LOGFONT {<br />
public int lfHeight;<br />
public int lfWidth;<br />
public int lfEscapement;<br />
public int lfOrientation;<br />
public FontWeight lfWeight;<br />
public byte lfItalic;<br />
public byte lfUnderline;<br />
public byte lfStrikeOut;<br />
public FontCharSet lfCharSet;<br />
public FontPrecision lfOutPrecision;<br />
public FontClipPrecision lfClipPrecision;<br />
public FontQuality lfQuality;<br />
public FontPitchAndFamily lfPitchAndFamily;<br />
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 32)]<br />
public string lfFaceName;<br />
}
Any help or ideas on what I'm doing wrong would be great!

My application uses a 3rd party component to do serial comms. As part of the initialisation routines of this component it generates an exception.
If I am debugging then this exception takes ages to be caught. The release version takes no time at all.
Why does the first exception take so long, and is there anything I can do about it?
|
|
|
|
|
I would run this by the Visual Studio team in the MSDN forums. Most likely it is due to some COM-related issue, possibly attempting to be caught by a managed debugging assistant. Have you tried turning off MDAs temporarily to see if that affects it at all?

Hi, it's me again 
I have function in an unmanaged DLL declared this way:
unsigned int CWB_ENTRY someFunc();
The CWB_ENTRY is expanded as _System (in a #define preprocessor directive). Anybody knows what calling convention is this?
Thank you.
