If you open a file with ShellExecute()[^], it will be opened by the default program associated with it. The file can also be a HTML file.

Use SQLConfigDataSource() with ODBC_REMOVE_DSN.

Hi,
I am usinf the CRegKey class of ATL but when I am compiling it is showing the error
error C2039: 'QueryStringValue' : is not a member of 'CRegKey'
C:\Program Files\Microsoft Visual Studio\VC98\ATL\INCLUDE\atlbase.h(4714) : see declaration of 'CRegKey'
Can anybody tell me whats the problem.
Thanks in advance.

It seems you forgot to include header file.
|
|
|
|
|
Not the case. Here's the error message again:
C:\Program Files\Microsoft Visual Studio\VC98\ATL\INCLUDE\atlbase.h(4714) : see declaration of 'CRegKey'
It's clear from the error message that the correct header was included.

Hi,
Can you tell me which header file to use.
Dhiraj Kumar Saini

You're already including the correct header. See here[^].
Steve

Do you check that this function really exists in CRegKey? May be you are using incorrect case somewhere or the function is not really there in the CRegKey. Or could also be the case of a missing header file.
Somethings seem HARD to do, until we know how to do them.

Again and again, you're using the MFC version with ships with Visual Studio 6 and pretending it has the same features of later versions. Can you see QueryStringValue method in this documentation page [^]?
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Hi all,
i have a application(Exe) which will load 2 dlls A.dll and B.dll, A.dll will create a map table(STL Map object) i have to use this map object in B.dll how should i do this ?
Using pragma Data section or using Memory map files ?
Thanks in advance

This is quite a complicated thing and there are may ways to do it and many pitfalls. If your not sure how to do this (and perhaps even if you are) perhaps it's best to use an existing library such as Boost.Interprocess[^].

If both A.dll and B.dll are in same process, you dont need to share it using #pragma . Just declare the variable as global and export it in the A.dll.
Also you please note the below two points
1. Sharing the data segments using #pragma is used to share a data in a dll across multiple process. Not between two dlls in same process or multiple process.
2. You will not be able to share a map using shared section, because the map will be holding pointers to many dynamically allocated memories, which is valid only in corresponding process. Trying to access it from another process result in access vialotion.
