I'll try that, but as I wrote earlier, taking the entire line out had no effect - it worked the same in one project, and crashed the same in the other.

Have you stepped into the AfxMessageBox() code to see how the caption text is obtained? That's the key to your question.

Add/modify the string resource (id = AFX_IDS_APP_TITLE) in your string table. AfxMessageBox() will use the value of that string when it displays a message box.

I am trying to create an application which serves as a general form to accept input. The form contains a button, that when pushed, outputs data as well as generates a popup window displaying a graph of the input data. I have created the input form but need help implementing the popup window with the graph.

DeleteFile to Recycle Bin???

Is there a way to delete a file to the recycle bin? DeleteFile simply deletes the file. Do I have to perform a MoveFile?? In that case, what is the macro name for the recycle bin?? For instance, move to system directory I think would be MoveFile("C:\\myfile.txt", //SYSTEM)???

You'll want to use SHFileOperation() here.

Could someone send me a sample program that loads font from a file (not already installed in Windows) and write text using that font? Also, to dump the displayed text in the loaded font to an image file (gif,jpg, bmp)...

Thanks

getting an int64 out of a hex string

ns11-Aug-04 6:37

11-Aug-04 6:37

I have string "0xFF070FF07" and I need to extract the int64 from it. I did try breaking up the string into high and lo parts and then bitshifting but I dont get the right value.
<pre>
unsigned __int64 alg_mask;
char *pHi,*pLo;

pLo = pHi + strlen(pHi) - 8;

unsigned int lo = strtoul(pLo, 0, 16);

*pLo = 0;

alg_mask = strtoul(pHi, 0 , 16);

alg_mask << 32;

alg_mask += lo;</pre>

How do I get my value out?
Thanks,
sb

What about StrToInt64Ex()? Rolling your own is also very easy.

Information logging

This is more of an implementation question . I figured that the Gurus here can help me out .
I m working on an App thats like a diagnostic tool in VC++(SDI app) . There are different screens(windows shown) that have a variety of information that could be packaged as a summary or report or like a log .

My idea of implementing this was like :

All the screens (Windows) derive from a CDataLog class that has a method called :
AddToLog(string data)
All this func does is dump data to temporary text file .

When the user wants to see the Log this file is read back and displayed in the view . Is this a good methodology ? I plan to delete the file automatically once I ve drawn it on the View . How can Programmatically do this ? Plus for the File I/o does using MFC classes have an advantage over my intended raw C implementation (using FILE * , fopen , fprintf etc )

Shut down a service programmatically

Well,

We know that services are not like a process, yuo can't just kill them.
So, how can we shut down a service programmatically ?

Thanks,
Shay

"net stop <servicename>" should would. You can use ShellExecute for this purpose.

Great answer, but....
Why it is not compiling ?
I tried the simple exmaple from MSDN and it will show SC_HANDLE as error.

Do I need to compile differently ?

Why wouldn't printf compile for me ?????

{<br />
 	int nRetCode = 0;<br />
<br />

CComBSTR to string

Hi,

I'm having a terrible time just trying to convert a CComBSTR to a string not char *, but string from <string.h>. Can anyone help? Or how about VARIANT to string - but I think its the same problem because it seems that I have to use the bstrval property of a VARIANT.

Re: CComBSTR to string

You can use OLE2A macro, for example,

USES_CONVERSION;
CComBSTR bstrSource = "Text to convert";
std::string sTarget = OLE2A(bstrSource);
