hello!!

i want to read a CString into an not existing .txt-File:

CString MyCString = "The Text";
CStdioFile csf("FileName.txt",CFile::modeCreate | CFile::modeWrite |CFile::shareDenyNone);
csf.WriteString(MyCString);

everything works fine (special thanks to PJ Arends Smile | :)

), but now i will set a path. at the moment the txt is saved in my Program file (MyProgram). now the .txt-file should be saved in MyProgramm\TXT-File.

how can i do this?

thanks
sunny

you can put whole path into construktor(or Open function)
CStdioFile csf("c:\\path\\FileName.txt",CFile::modeCre.....
Or if you need you program path you can retrieve it by:
GetModuleFileName(NULL,... function.

that´s good, but i have another problem:

the filename is given from the program user:

<br />
CString FileName=m_EditFileName;<br />
FileName+=".txt";<br />

i tried this:

<br />
CStdioFile csf("TXT\\myfile1.txt", CFile::modeCreate ...);<br />

and it works perfect. (thanks).
but now i in need something like this:

CStdioFile csf("TXT\\"FileName, CFile::modeCreate ...);

but this do not work? what can i do??? what´s wrong?

thank you for reply

Almost right, change to:

...
CStdioFile csf("TXT\\" + FileName, CFile::modeCreate ...);

Try it like this:

<br />
CString FileName = m_EditFileName;<br />
FileName += ".txt";<br />
CString FullName = "TXT\\";<br />
FullName += FileName;<br />
<br />
CStdioFile csf((LPCTSTR)FullName, CFile::modeCreate ...);<br />

Any reason you're doing the cast from CString to LPCTSTR here? It does an implicit cast already, eh?
I never do it, but I have seen others do it, so I'm just wondering what your reasons are?
Thanks Big Grin | :-D

That's why I ramble so much. If you're short and quotable, there's a much greater danger of ending up in a sig.

CString MyCString = "The Text";
CStdioFile csf(".\\FileName.txt",CFile::modeCreate | CFile::modeWrite |CFile::shareDenyNone);
csf.WriteString(MyCString);

With the include headers this works...

could it be...

Hope this helps...

database problem

Hi All,

I am opening database as
CDaoDatabase dbSql;
dbSql.Open(NULL,FALSE,FALSE,"ODBC;DSN=ITITest;UID=sa;pwd=");
CDaoRecordset rsSql;
rsSql.m_pDatabase = dbSql;
rsSql.Open(dbOpenSnapshot,"SELECT * FROM tbltest");
BOOL TRY1 = rsSql.CanUpdate();

rsSql.SetFieldValue("test1","123");

when this is executed TRY1 is 0, that means I cant update
I have to change the data in one field of tbltest at the run time for which I am using SetFieldValue of CDaoRecordset.

I am getting following error,
"operation is not supported for this type of object"

Is this approach is correct?? Can anyone explain me asap

Thanks in advance
Uday

IMSAdminBase

I need to use IMSAdminBase in order to programatically administrate IIS. Unfortunately i get unresolved external symbol on linking phase.
Do you know what is the appropriate library file to be used?

What is the unresolved external?

According to the docs, IMSAdminBase only requires

#include "iadmw.h"
and
#include "iiscnfg.h"

As it is a COM interface, I wouldn't expect there to be a static library to link against.

It's a MFC dialog-based application in DEBUG mode. I have included the headers in stdafx.h.

Try adding

#define INITGUID

before the #includes.

I did. No effect.

I have used the informations from MSDN - Enumerating Keys and Data[^] (hope the link is ok) where something is obviously missing...

Remove the includes from stdafx.h and place them in stdafx.cpp instead.

Not a chance. It gives me compile errors and among them i've noticed:

C:\temp\t\iis\iisDlg.cpp(230) : error C2065: 'CLSID_MSAdminBase' : undeclared identifier
C:\temp\t\iis\iisDlg.cpp(231) : error C2065: 'IID_IMSAdminBase' : undeclared identifier

Solving these problems is turning me back to the linking errors Dead | X|

VC++ Template problem

VC++ 6.0 has a problem with templates I'm told. what is it?

It does not support partial template specialisation, which in particular, means you cannot do the sort of template metaprogramming which has become trendy since the 'Modern C++ Design' book came out. While it is a pain, ( and still not fixed in VC7, yet ), it really doesn't stop 95% of the dev work likely to happen using templates.

Again, you can screw up a C/C++ program just as easily as a VB program. OK, maybe not as easily, but it's certainly doable. - Jamie Nordmeyer - 15-Nov-2002

I ask because with the free compiler DEV-C++ I had a very very basic swap function, and the code would not compile under VC++ when copied in to it.

Shouldn't be a proble. The best approach would be to post the code, so we can comment. Remember to tick the box under this main edit box that says 'display this message as-is (no HTML)', or anything between <> will be lost.

lol sorry I meant I had the code - ages ago.

template<typename x>
int Temp1(X &A, X &B)
{
X Var;
Var = A + B;
return Var;
}
