How about trying to rename _MESSAGES_TYPE, NUM_MESSAGES, and FeatureSetTable. May be there is a macro with these names some where else.

Well, it appears that it's important where the code posted lives in the class. I'm still not sure what the problem was (maybe some trash text I didn't see someplace). Anyway, I moved the code to the end of the class, and it built fine.

How to redirect com port data stream to my application.

You can read from the COm port using CreateFile() and ReadFile(). See here.

Thanks for the reply. Actually I'm not reading/writing the com port but
intercept data sending to com port.

thanks
but I have seen this "link" before and i couldn't figure that out in my problem .
I tried to define the register type key first then assign it to some value like this:
const short REG_OPTION_NON_VOLATILE;<br />
REG_OPTION_NON_VOLATILE =0; but it didnt work .
so iam stuck now at this point.
pleeease ... help me
again ...thank u.

I am having trouble setting the precision of a double in a Windows Forms Application. I would like to set the value of temp in this label to 2 decimal places. I know there's an easy fix for this, but after searching I just can't find how to do it.
label4->Text = "The output of your conversion is: " + temp + "\u00B0";
Thanks for the help!

You have to do temp.ToString("format-string"). Check the help of Double.ToString[^] for more details.

I believe that would be a static control.

Greetings,
I thought this:
hbmTiles = WinGCreateBitmap(hdcBackbuffer, &bmi, (void**)&ptrTiles);
...would put the pixel data of hbmTiles into ptrTiles. And it works, the pointer does indeed contain the correct pixel information, but if I write to it, nothing happens to the original bitmap. How can I apply this back to the bitmap?
Thanks in advance!

I have written a C++ Windows program called MAKEOBJ. It is a CGI mesh handling program. Under Windows Vista it is displaying an odd bug. In it, when I call SetPixel(dc,x,y,color), the pixel seems to be set only if (x&256)==0. This x is relative to the program's window, not to the whole screen. This happens with my MAKEOBJ's old Borland C++ version (which behaved OK under Windows 98 on my old computer) and with my new Visual C++ version. (Line drawing, and copying an image to the screen, work OK.) Please what is happening and how to cure it?
The same also happens with a completely different program that I wrote, to handle 2D graphics images.

Try GetLastError and see what is the error returned from GetPixel, if any?

I think may be it comes with compiler problem ..
|
|
|
|
|
|
The cause is not a "compiler issue", because it happens with Visual C and Borland C, as my first message in this thread says.
Could the cause be a replacement screen-driver which I had to download and install? The fault symptoms are relative to the affected program's window, not to the whole screen. Line-drawing and BitBlt and similar seem to run OK.

I have hacked a temporary solution, thus, but I would prefer a proper permanent solution:
void Set_Pixel(HDC dc,int x,int y,COLORREF c);
#define SetPixel(dc,x,y,c) Set_Pixel(dc,x,y,c)
/*-----*/
void Set_Pixel(HDC dc,int x,int y,COLORREF c){
HPEN p=CreatePen(PS_SOLID,1,c),q; q=(HPEN)SelectObject(dc,p);
MoveToEx(dc,x,y,0); LineTo(dc,x,y+1); SelectObject(dc,q); DeleteObject(p);}
