that fixed it. so when passing parameters from special libraries, include the .h file in the function prototype .h file.
thanks,

Recently, I downloaded a sample program from the internet which after compiling it, received a "0 error; 0 warning" result. When I ran the program, it produced a screen (something like a menu) with several options from which to choose. As soon as I selected one of the options (it didn't matter which one), the screen disappeared.
Checking Windows Explorer to see the ".exe" file for the program, I noticed there weren't anything. NOTHING!! There were no ".pch", ".ncb", or ".obj" files (etc.). NOTHING!!
Was there something the author of the program turned off to suppressed the creation of those files, and why did it execute nonetheless (producing the menu screen)?
Is there something I can turn back on to get those files created?
Thanks for any pointer.

They were created, but possibly in a different location. Do another compile and then search for the EXE. Or you could inspect the .DSP file to see if another target folder was specified.

Thanks for replying.
Your suggestion about searching for another location where the files may possibly be at, turned out to be a very good tip, because doing so revealed the place where the ".exe" file (along with the others) were located.
Having found the ".exe" file, I once more clicked on it and true to form it produced the menu screen. This time however, it didn't wait for a selection to be made before disappearing, it did so automatically the very next second after it came up.
It's like the author did not intend for the person to use the application, but only see the menu.
Thanks again for the good tip you gave.

Hi,
Still working on the program that sends messages over the internet. 
The problem that I am facing now is inserting a delay. I need to insert a delay between sending numbers when i read from a file. The file just contains a bunch of numbers, each on their own line. I need to just put some delay that the user will set in another dialog box.
Any ideas on how this is possible? Please help if you have any information.
Thanks for your help.

Use a Sleep() before opening the file.

Hi John,
I need to have the delay while reading the file. I need to read a few numbers from the file, then delay for some amount of time (which is determined by the user in another dialog box) and then read some more.
Can someone tell me if this is possible? if so, can someone lead me in the right direction. sample code maybe?
thanks for the help.
Jimmy

It should be pretty easy to do. Is there a chance that the delay will be long > a few seconds? The reason why I ask is it is very easy to add a Sleep(). In the simple case during the Sleep() the window will not be updated at all. If the user trys to minimize or move the window it will appear hung. If this is a problem then we will have to go about it in another way. The other question is how are you openining the file (CFile, ifstream CreateFile() ...)? There are so many functions to use.

John,
Sorry for not giving you the information you need to help me. I have been trying to do this in between doing my HW.
Well I have an app done in MFC, with a lot of dialog boxes. I connect to the server and have to send these numbers to the server. The numbers are all different basic math calculations. Any how I write the numbers to a file, each one having its own line. My program is supposed to send all the numbers to the server, but here is the problem. The user can choose to add a delay in sending the information. So it should send one number, then delay for a short time, then send the next then delay for the same amount of time.
The time is going to be no more than 1 second, and more like to be in the range of 0.1 - 1.0 seconds. Is this possible? I know it really short of a time, but that is what i was told.
I open the file as:
CStdioFile f;
f.Open(Filename, CFile::modeNoTruncate | CFile::modeWrite);
f.WriteString(temp);
f.Close();
MANY MANY thanks.... I really appreciate this. I need to get this app done soon.

I assume you know how to connect and send data to the server 1 number at at time. Convert the user delay value into milliseconds. Then before your Send() function call Sleep(userTime).
Here is a link that talks about the accuracy of sleep:

I hope this answer is not too simplistic. I get the idea you want more but I am not sure what.

Currently I am using an overloaded function that uses a void pointer and the length of the pointer. However I am having an issue as the output cannot contain nulls and in a few cases it does. I need to strip/replace the nulls in the pointer so they don't show up in the output. I have included a brief snipit to give you an idea of what I am trying to do.
Current Code
note - openfile is CFile object
---------------------------------
FunctionX(void* buf, ASInt32 bufLen)
{
DURING
openfile.Write(buf, bufLen);
}

Your response was not entirely helpful or appreciated. I am not even sure what you meant by it. If you are trying to imply that I am missing something obvious please enlighten me.
I have had a crash course in C++ over the last 2 weeks and I believe the solution to be simple. I simply need to remove/replace on the nulls and output the remaining text to a file. I have no idea how to accomplish this from C++ when I am starting with a void pointer.

Agreed. That attitude seems to be a common post from him/her.
Anyway, you could have something like:
FunctionX(void* buf, ASInt32 bufLen)
{
LPBYTE lp = (LPBYTE) buf,
b;
b = new BYTE[bufLen];
for (int y = 0, x = 0; y < bufLen; y++)
{
if ('\0' != *(lp + y))
b[x++] = *(lp + y);
}
openfile.Write(b, x);
delete [] b;
}

Hello,
Just wondering if one of these ways is better than the other? And why?
char sTest[256];
lstrcpy(sTest,"testing");
CString strTest = sTest;
or
CString strTest;
strTest.Format("%s",sTest);
Thanks,
Rob

Huh ?
CString strText("Testing");
or did I missed something ?
