hi,
say for example,
i have created one database application in vc, and i access the MS access database through that.
so first i create a DSN from control panel\odbc datasources.
obviously i have to access that database through the dsn from vc++.
now if i want to install it on my clients machine, i have to copy the files first, then map the DSN and then run the application.
now what i want is, is there any method to automate the creation of DSN, such that, just by a single click on my application, this DSN gets created.
thanks.

There are a lot of setup-generation suites that allow you to start scripts during the setup-process.
One of these is NSIS[^], and its free even for commercial use.
There are many others. Just google.

thanks for your reply.
i shall verify the tool.
but i wanted some code snippet which can create the dsn if i supply the database filename and dsn name.

To be honest, I have not the faintest idea what 'dsn' is.
But as you seemed to know how to make one, I showed you a way how to automate that on your client computers.

DSN means Data Source Name(I also have known it today!) . I guess it is the name that C++ will use in connection to a driver to a database.

And DSN's are just about competely useless in todays environment...
Unless you're actually going for lower performance and a more "generic" approach to database work.

Yes, but why not just use a DSN-less connection?

To configure data sources programatically, see
Installing and Configuring the ODBC Software[^]
particularly the sections "Configuring Data Sources" and "Registry Entries for Data Sources".

Hi all,
What can I do to prevent the following:
Invalid Cursor State Error with the MS Oracle ODBC Driver
I have visited this link: Invalid Cursor State[^] and tried what they suggested, i.e: If using the ODBC API directly, call SQLPrepare() before calling SQLExecute() and SQLExtenedFetch() to refresh the recordset. But it is not working, I still receive the error. I have notied that if I create a new recordset for each sql statement is works, but that creates huge memory leaks.
Can anyone please help me ???
Many Thanks

try using the pretranslatemessage handler.
but here, you have to implement your own logic.
any mmore clarification required, get back.

Did you use of PreTranslateMessage .
|
|
|
|
|
The use of PreTranslateMessage() *might* work, but most implementations are incorrect. The other downside is that it permanently ties the child control to the parent. A better solution is to derive a class from CEdit. Override the OnGetDlgCode() method and return DLGC_WANTALLKEYS. Then override the OnChar() method like:
void CMyEdit::OnChar( UINT nChar, UINT nRepCnt, UINT nFlags )
{
switch (nChar)
{
case VK_RETURN:
GetParent()->SendMessage(some_custom_msg, GetDlgCtrlID(), (LPARAM) this);
return;
}
CEdit::OnChar( nChar, nRepCnt, nFlags );
}When the edit control "sees" the Enter key, it posts a message to the parent indicating such. The parent can then respond accordingly, if at all.

How early can a Windows service start up?
Comparing the below:
1) a Windows service application (an NT service),
2) a PCI bus device driver,
Can a Windows service be started up earlier than a PCI bus device driver?

write this line in OnInitDialog function.
ModifyStyle (NULL, WS_MINIMIZEBOX);
Hope this will work.
By the way, why don't you just change your dialog style from child to popup ?

I know about the Two ways of making the .DLL.
1)extern "c" _declspec(dllexport) funX() {} and
2)Throught .Def file in which we are Writing only function names we want to export
EXPORT<br />
FunX @1
I have Some Question about that.
1)What is/are the diffn betn them and
2)What mean by extern "c"
3)"@" what is indication of this symbole. I tried without it and Dll Works Fine.
