...but how to use with a single TCHAR? This macros uses strings (more than a single char) and no single chars.

Because casting does not convert between character sets. What I'd do is read the data into a buffer (keeping it as MBCS), zero-terminate it, then put it in a CString which will convert it for you properly.

I am trying to capture a bitmap or an icon from a .bmp or .ico file selected by a user from a standard CFileDialog dialog.
LoadImage() always fails (returns 0 and hBitmap or hIcon are NULL).  
CString strAppPath;<br />
CSString strImagesDirectory;<br />
CString pathName;<br />
CString fileName;<br />
CString extName;<br />
HICON hIcon;<br />
HBITMAP hBitmap;<br />
<br />
CFileDialog dlg(TRUE, NULL, NULL, OFN_HIDEREADONLY, "Bitmap(*.BMP)|*.BMP|Icon(*.ico) <br />
*.ico||", this);<br />
if( dlg.DoModal() == IDOK )<br />
{<br />
pathName = dlg.GetPathName();<br />
fileName = dlg.GetFileTitle();<br />
extName = dlg.GetFileExt();<br />
<br />
if (extName == "ico" || extName == "ICO")<br />
{ <br />
hIcon = (HICON)::LoadImage( NULL, pathName, IMAGE_ICON, 0, 0, <br />
LR_LOADFROMFILE|LR_DEFAULTCOLOR ); <br />
if (hIcon)<br />
SetIcon(hIcon, TRUE);<br />
}<br />
else<br />
{<br />
hBitmap = (HBITMAP)::LoadImage( NULL, "C:\\HAPPY.BMP", IMAGE_BITMAP, 0, 0, <br />
LR_LOADFROMFILE|LR_CREATEDIBSECTION);<br />
if (hBitmap)<br />
bmpImage->Attach(hBitmap);<br />
}<br />
<br />
}
I have tried a number of things with the second parameter of the LoadImage() call -- hard coded path to the file, path as captured by the CFileDialog, image files in the root directory and located in a variety of other locations (including the directory of the working project). Nothing works. I have searched the documentation and what I have should work.
I am working on Windows 2000 Professional and in Visual Studio .NET but in unmanaged C++ code.
Anyone have any idea whta I am doing wrong?

The first parameter should be the instance of your module. Passing NULL instead is only for OEM images.

This is one of the things I have tried. I tried it again after I got your response. No luck. 
I changed the code to look like this:
CFileDialog dlg(TRUE, NULL, NULL, OFN_HIDEREADONLY, "Bitmap(*.BMP)|*.BMP|Icon(*.ico)<br />
|*.ico||", this);<br />
if( dlg.DoModal() == IDOK )<br />
{<br />
pathName = dlg.GetPathName();<br />
BYTE FileBuffer[10240] = "";<br />
fileName = dlg.GetFileTitle();<br />
extName = dlg.GetFileExt();<br />
<br />
HINSTANCE hInst = AfxGetInstanceHandle();<br />
<br />
if (extName == "ico" || extName == "ICO")<br />
{ <br />
hIcon = (HICON)::LoadImage(hInst, pathName, IMAGE_ICON, 0, 0, <br />
LR_LOADFROMFILE|LR_DEFAULTCOLOR); <br />
if (hIcon)<br />
SetIcon(hIcon, TRUE);<br />
}<br />
else<br />
{<br />
hBitmap=(HBITMAP)::LoadImage(hInst, "C:\\HAPPY.BMP", IMAGE_BITMAP, 0, 0, <br />
LR_LOADFROMFILE|LR_CREATEDIBSECTION);<br />
if (hBitmap)<br />
bmpImage->Attach(hBitmap);<br />
}<br />
<br />
}
I know I am getting a valid HINSTANCE.
Any other suggestions?
BTW -- I really do appreciate the help.

Boy, I sound like my children (no, that won't work)
I did try that -- This is one of the documents I found that discusses LoadImage(). The problem remains the same. When I add this code to my own, then the LoadImage() call in the LoadBitmapFromBMPFile() fails.
BOOL LoadBitmapFromBMPFile( LPTSTR szFileName, HBITMAP *phBitmap,<br />
HPALETTE *phPalette )<br />
{<br />
<br />
BITMAP bm;<br />
<br />
*phBitmap = NULL;<br />
*phPalette = NULL;<br />
<br />
<big>*phBitmap = (HBITMAP)LoadImage( NULL, szFileName, IMAGE_BITMAP, 0, 0,<br />
LR_CREATEDIBSECTION | LR_DEFAULTSIZE | LR_LOADFROMFILE );</big> <br />
if( *phBitmap == NULL )<br />
return FALSE;<br />
I think there is something going on with LoadImage() itself. I thought that the .bmp files I was using to test might be the problem because they are very old and have not been updated. I got a .bmp with lots more information stored in the properties and it does not work either.
The only thing I can think of is that LoadImage() fails on Win2K. I read a Microsoft Knowledge Base article to this effect http://support.microsoft.com/default.aspx?scid=kb;en-us;Q329092. I do not have access to a Win9x machine with Visual Studio installed to test this theory.
Thanks though.

What does GetLastError return after you call this function and it fails?

Funny you should ask.
I just added a call to GetLastError() a few minutes ago and realized that I had created a CFile (to get size information), opened it, read the contents of the .bmp into a buffer(in an attempt to get LoadImage() to work) and then closed it after I attempted to call LoadImage() -- GetLastError() returned 32 (ERROR_SHARING_VIOLATION). I moved the CFile::Close() to before the call to LoadImage() and now all is well.
It was a dumb thing to over look. Wish I had tried the GetLastError() sooner.  Oh well.
Thanks for all of the help.

Hi
the last few weeks I modified some files in my Platform-SDK directory, resulting in linker errors and missing files 
Now I have uninstalled the latest Platform SDK completely and reinstalled it again, but I still keep getting this error (German):
C:\PROGRAMME\MICROSOFT SDK\LIB\LIBC.lib : fatal error LNK1112: Computer-Typ "IA64" fuer Modul steht in Konflikt mit dem Ziel-Computer-Typ "IX86"
This seems to me to be a conflict between 32bit and 64bit libraries. My project is build for 32bit platforms.
But the first library path the compiler should use is defined as C:\PROGRAMME\MICROSOFT SDK\LIB\, that's why I don't know how the error can occur.
thanks in advance

Try to find this path in the registry, and modify it or kill it.

Hello,
I want to ask how to store a String in 2-D array foramt?
e.g.
abc[0][0]="A";
abc[0][1]="AA";
abc[0][2]="AAA";
......
....
..
abc[n][n]="AAAAAAAAAAAAAAA";
THX!!!
I am not using MFC, just the console mode!!!
I think it for a long time!!!
|
|

|

If your 2-D array will simply hold literal strings, like in your example, declare it as a 2-D array of pointers to characters, like this:
char* abc[N][N];
This assumes N is a predefined constant value.

I am developing for a Windows CE device in which there is a bug where files that are divisble by 2048 aren't copiable from the permanent storage to the volatile storage. At this moment I have been just checking to see if the exe's and dll's are divisible by 2048 and if so add some characters to the end of the file. Is this a safe practice or should I be doing something else.
I have tried putting an int padding[] = {0, 1,..., etc} in the file but it seems the file doesn't change in size; which, I could only assume is the optimizing compiler removing it.
Cheers,
Clint

I'm sure that there is a linker setting for this, but I can't remember it at all...
And, for the padding, for the compiler optimizer do not remove it, try do something, like reading all the array in a for loop...

I was trying to get Googles webpage by using Winsock. But the real problem is I am behind Firewall (Microsoft ISA). As far as the Winsock is concerned getting webpage within the Firewalll is not difficult. But when I try to access behind the Firewall the Server won't allow me anymore.
Please anyone can help regarding how can I access a webserver behind firewall by using Winsock. How can I use or implement Proxy support in my program.

You should check out the relavent RFC on supporting a HTTP Proxy. For an example of winsock programming which works thro a HTTP proxy, check out my CDDB class at http://www.naughter.com/mfccddb.html

hi
it's my third time posting this question in as many days! I wrote my own wave file, but when i want to play it with sndPlaySound, i only get a beep from the PC speaker. Other applications play the file fine, and other wave files are played with the sndPlaySound function in my app.
WHAT'S WRONG?
PLEASE!!

Send me the file and the snippet of code that plays it.

Is there a system type command in MFC? Or do I have to use system to launch another application from within my application?
Thanks
