I have this same environment at home and have no troubles compiling (this is in contrast to Michael's comment about Microsoft disabling the product). Perhaps you need to reinstall SP5 with the thought that it might provide the "correct" resource compiler.

What happens if you run the resource compiler from a command prompt? Change to the C:\Program Files\Microsoft Visual Studio\Common\MSDev98\Bin folder, type rc, and see if it gives you the "...\rc.exe This program expects..." or the RC1107 message.

hi,

NOP, the same message. I copied rc.exe and rcdll.dll from visual stidio 6 to platform sdk/bin. It works ok, but i know it is not right.

Any thoughts ?

MS purposely crippled it so it will not run on 9x/Me. Frown | :(

If you have access to older Platform SDK CDs, go back to around Oct 2001 or so and grab the RC.exe from there.

Reading a .csv file

Hi,
How can I read raws and columns of a .csv file?
I would like to move from one column to the next,, how can I do that ?

The raws (rows) of the file can easily be read with CStdioFile::ReadString(). The columns can be handled with AfxExtractSubstring(), or CString::Find(). There's more than one way to skin a cat, however.

how do I use those commands in my code
right now this is how I read my .csv file

ifstream infile(file1);

char temp[500];
infile>>temp;

// so now i want to move to the next row or column, how do I do that with your syntax?

Thanks

Very seldom do I use streams so this might not work, although it should get you close:

istream in;
while (in.eof() == 0)
{
    is.getline(temp, sizeof(temp));
    // now do something with the line just read
}

How to change from WORD to CString

Define "not working."

Some things that struck me as odd:

float atol;

Not sure what you are trying to accomplish here.

int main(int argv, char ** argc)

Traditionally, argc is the number of arguments, while argv is the argument vector.

if( XOR(argc[1],(unsigned int)atol(argc[2]) ) )
int XOR(char * filename, unsigned long key)

In the call to XOR(), the second argument is being cast to an unsigned int, while the function's prototype is expecting an unsigned long.

How can I use the AlphaBlend()GDI function on a GDI Rectange() function on the screen to make it transparent. Is there some sample code to do this?

Thanks

Search for AlphaBlend or Transparent at codeproject. There are articles, FAQ, and totorials that cover this subject.

Hi,
In my code, i read the system date with the following code,

SYSTEMTIME systime;
GetLocalTime ( &systime );

WORD day = systime.wDay;
WORD month = systime.wMonth;
WORD year = systime.wYear;

now, I would like to store it in this format, day/month/year as CString,.
how can I do that?

WORD year = systime.wYear; 

CString strDate;
strDate.Format("%u/%u/%u", year, month, day);

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

In the MFC try CTime::Format or strftime for Win32

I agree with the previous poster. If you are using MFC either use CTime or COleDateTime and they both have a function to convert the time to a string in whatever format you need.

Hi !

We are developping an application in C++ with Visual Studio 6 SP5.

I'm compiling my application in Debug mode.
Since a few hours, when I run (with CTRL+F5) my application, it crashes. I have no idea why.
When I try to debug, and run it with F5 (debug), my application does not crash !

Doing some tests, I realised that showing a dummy message box at a certain point in my code make it work !

And, if I compile my application in release mode, it works fine !

My collegue, who is working on the same application doesn't have this problem. If I try to copy his sources directory in my own directory and to rebuild my app, I still have the problem.....

Any idea what's going on ????

Thanks !
Jerome

Where? Is it at a certain point when you are interacting with it? Does it happen before a particular dialog is displayed? Define "crashes." Is this an unhandled exception? Does it also happen when ran from outside of the IDE?

No, but this article might help.

Thanks, but as I said, the release version works fine. Only the debug version is crashing. If I execute the debug version (ctrl+f5) it's crashing, if I debug the debug version (f5) it's not crashing.

Ted Ferenc9-Jan-04 4:34

It sounds like you are overwriting some memory location, the debug version is probably checking for this whereas the release version is not.

Assuming this is the reason it could be a M$ fault or one of yours, in cases like this I like to run the code through a program like Bounds Checker, it might solve the problem, it generally finds a few "bugs" for you that you did not know about!
