Which is not an error, but means that more data is available.

thanks for the reply. But I am already making sure that buffer size is enough to store the data...by API 'RegQueryInfoKey()' I am getting max length of value's data.. I am executing it before 'RegEnumValue()' and allocating the buffer for value (length returned by 'RegQueryInfoKey' + 1)... still why 234 error ?

I just traced my code and found that for every character it's taking 2 bytes.. and I am allocatiing buffer as per length returned by 'RegQueryInfoKey' which returned length of longest value data... for example actual date string/data(REG_SZ) length is 20 but when 'RegEnumValue' gets the date string/data, the length returned is 40(in last param of 'RegEnumValue').... So I doubled my buffer's size but still it gives me same problem... any suggestions ? I am running my 'console' appln on 32 bit intel proc with 32-bit XP OS on it...

I resolved the prob, after each call we need to set the data buffer size back to max value length... sadly this is not quoted in MSDN! it's hard to understand whats going on wrong in code when MSDN says everytime 'RegEnumValue' iterates thru reg values,it returns the data length... I wasted my night for this silly problem...

With moving the file or figuring out what your temporary folder is?

Use the GetTempPath() function to retrieve the path of the temporary files directory - see the documentation here.
Then to copy the file use the CopyFile() or CopyFileEx() function to copy the file to the temporary directory.

Hi,
I'm in need of a conversion routine to convert a string into a integer(long). I'm relying on CRT function _tcstol to do this. Below shown is my approach:
main()
{
_TCHAR *q = 0;
char txt[] = "5x";
long l = _tcstol(txt, &q, 10);
if (q && _tcsclen(q))
{
cout<<"Invalid Integer";
}
}
I'm relying on parameter2 in _tcstol to validate a integer. (i.e)the endptr Pointer to character that stops scan.
Will this approach work fine in all cases?
Thanks in Advance

Hello,
yes, I would do the same as you did for converting a string to an integer. By the way, have you looked at this thread[^]?

Hello,
I do not know if there is an easy way to solve your problem. I think you need to call CWnd::SetFont[^] method for all your dialogs.

You can make your font with CreateFont and then use of SetFont for your controls.

Okay so I need to use the linked list class provided in the standard template library but when I do I get the error message "fatal error C1083: Cannot open include file: 'iostream.h': No such file or directory.
C:\Program Files (x86)\STL\include\stl_algobase.h Line 57"
For some reason this file wasn't provided with my copy of Visual Studio 2008 (Express Edition) I did however get the file "iostream" distributed with visual studio but renaming this is futile as the two files are fundamentally different.
What to do? 
|
|
|
|
|
The headers whose names end in .h are from the (very very) old standard library. In fact, it sounds like 2008 doesn't even ship them anymore. Use the files without an extension.
|
|
|
|
|
the problem is that the file is #included in stl_algobase.h. I can manually change it but it breaks the STL. Am I missing something here? Am I meant to be using a list class that is already included with visual studio or is the STL list the one I should be using?
|
|
|
|
|
Sounds like a bug in the Express edition. Are you running SP1?
If you don't get an answer here you could try posting on the MSDN forums. I can't believe something this basic doesn't have a fix.

I don't recall downloading a service pack for visual studio but according to the "About" entry in the help menu I am running version 9.0.21022.8 RTM.
I managed to locate the standard template library in my visual studio folder (Previously I was just looking in the microsoft windows sdk folder) so I deleted the copy of STL that I downloaded and made sure it was using the default one provided with my compiler. This seems to have fixed that problem but now when I compile I get the following error message
Error 1 fatal error C1189: #error : STL/CLR can be used only in code compiled /clr, clr:pure, or /clr:safe C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include\cliext\xutility 6
I have tried all three command line parameters but with each one I get one of the errors;
Error 1 Command line error D8016 : '/EHs' and '/clr' command-line options are incompatible cl<br />
Error 1 Command line error D8016 : '/EHs' and '/clr:pure' command-line options are incompatible cl<br />
Error 1 Command line error D8016 : '/EHs' and '/clr:safe' command-line options are incompatible cl<br />
/EHs appears to be embedded into the win32 build options and there seems to be no way for me to remove it (and I also have no clue what it is!)

Are you really trying to do a C++/CLI (managed) app or a native app?
For C++/CLI, you should be using /EHa
If you're using the IDE, it should be at
project settings/Configuration Properties/C++/Code Generation/Enable C++ Exceptions
For STL:
According to the Standard C++ Library Overview[^], <list>
may be the header file you want.
For STL/CLR:

I've never been sure of what managed c++ refers to but I'm under the impression it means working with the .net framework? If so, then no I am not writing a managed c++ app.
The header file you mentioned is the one I am now using as I posted earlier but that's what is giving me the new error "STL/CLR can be used only in code compiled /clr, clr:pure, or /clr:safe", and subsequently the other three errors when compiling with those switches.
So am I meant to be using the standard template library in a native c++ project or not? It doesn't appear to be compatible judging from the errors its spitting out.
Perhaps I should just write my own linked list template class.

Correct.

Yes. What I can't figure out is why you're getting an error that mentions
STL/CLR (which is for managed .NET code) if you're not compiling code managed.
Can you post some sample code using an STL list class that
fails?
