Your DLL is built with debug libraries. Debug libraries do not exist on a machine, by default.

I'm learning RPC (remote procedure call).
I included "rpcndr.h", and add "Rpcrt4.lib" in object/library modules. When compiling, I got the following errors:
Linking...
interface_c.obj : error LNK2001: unresolved external symbol _MIDL_user_free@4
interface_c.obj : error LNK2001: unresolved external symbol _MIDL_user_allocate@4
Debug/22_rpc.exe : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.
what am I missing? I am using VC6.0.
Thanks a lot for any help!

According to MSDN: The midl_user_allocate function is a procedure that must be supplied by developers of RPC applications. It allocates memory for the RPC stubs and library routines.
Example:
void __RPC_FAR * __RPC_USER midl_user_allocate(size_t cBytes)
{
return ((void __RPC_FAR *) malloc(cBytes));
}The midl_user_free function also must be written by the developer.
Example:
void __RPC_API midl_user_free(void __RPC_FAR * p)
{
free(p);
}Best wishes,
Hans

I see why it's called _user_ now. At first I thought it's my RpcRt4.lib which is not up-to-date.
Thank you very much, Hans.

What is the difference between VirtualAlloc and GlobalAlloc functions which are used to allocate memory from Heap. Also how is the heap management done given that there is no concept of Local and Global Heap.

Hello, does anybody ever tried to automate Excel in VC++ and want to show the autofilter programmatically? I tried Range.AutoFilter() function, however, I cannot make it work for me. I just want to get the drop-down arrow show up for me (similar to Data->AutoFilter menu in Excel).
Appreciate if anyone can direct me to a website which has more info on excel related application. Most of the sources I found is using either C# or VB, but limited info on C++.
Thanks a lot!

Hi, Can you please that Problem:
Maximum Clique Problem is a graph related NP-Complete problem. A Clique in an undirected graph G is a set of vertices V such that for every vertice pairs in V, there exists an edge connecting the two. Another definition of clique is given as the induced subgraph of V which is a complete graph. Also, Maximum Clique Problem is the corresponding optimization problem that is finding the the largest clique in a graph.
1) Find a subtle way to reduce Clique Problem to the Independent Set problem. (You should give the complexity of the transfer function in the report.)
2) Implement a software to solve the Maximum Clique Problem.
(You should give the complexity in the report.)
3) Implement a software which applies the appropriate transformation you have proposed and solves the problem as an instance of Maximum Independent Set problem.
(You should give the complexity in the report.)
Data and Test Runs:
Your software should be able to process any arbitrary graph which is represented by a NxN matrix in the input text file. A sample text file is provided within this project package (sample.txt). In this file, a value of 1 indicates the existence of an edge between vertex i and j. Your project will be tested both with this file and some other test files.

Why does the following code result in a deadlock?
#include <windows.h>
#include <stdio.h>
#include <process.h>
unsigned __stdcall thread(void*)
{
while(1)
{
printf("t");
}
}
int main()
{
unsigned dwThreadId;
HANDLE hThread = (HANDLE) _beginthreadex(NULL, 0, thread, NULL, 0, &dwThreadId);
while(1)
{
SuspendThread(hThread);
printf(".");
ResumeThread(hThread);
}
return 0;
}

It depends on how ::printf() is implemented.
I assume it uses a critical section at some point to block other threads from messing up the memory while executing. If my assumption is correct, it's just a matter of time before your thread is suspended while inside the critical section and your main thread will be blocked when calling ::printf() resulting in a deadlock.
You should consider suspending a thread from another thread a serious bug since you have no idea in what state the other thread is in. If the thread that is suspended owns a critical section it may not be released and you'll get deadlocks.

The handle must have the THREAD_SUSPEND_RESUME access right.

Hi every one
I am developing online jewellary shop site. It almost completed.
But i face one problem in my site there are 2 module 1 admin and 2 client.
now admin can add, delete and modify category and product and all the things which is available.
Now when ever i go to upload a new image of category or product at that time it is asking about username and password.
I am giving u My site URL and ID,Password and also full path pls follow it u will see practicly there
http://www.sarconsultancy.com/ddgadmin/
go here there id and password is 'admin/admin' both same
after login u will see Admin Home Click on Catelog
Now u will see 'category' page. click on 'Edit Image link' then 'browse' and select an Image and try to save it. u will see the dialog box which is asking for a username and password
now my question is why it is happening
i found that i have to set the permission of physical folder i also tried to set permission like 777, 750, and all the possibility but when i save and close smart ftp then it will be reset. means it becomes 0 again.
I am using Smart FTP Client if u know how to set the permission for physical folder on remote machine pls tell me totally process
Thanks
I am wating your reply

Why are you after that poor function? It walks all through MFC class hierarchy and it is a low level function. Don't mess with it.
Handle OnHelpInfo() (right click on your dialog in design mode, click events, then add a handler for WM_HELPINFO...)
BOOL CMyDlg::OnHelpInfo(HELPINFO* pHelpInfo)
{
AfxMessageBox("Help called");
return false;
}

1) Close the editor and try reopening it. Check if things work for you this way
2) Delete the .clw, .ncb and .suo files from your project directory and then try and open the solutions.
3) It could also happen if you have committed some mistake in the line(s) above.
4) If you are using Smart Pointer
etc etc.
These could be some of the possible problems and solutions to your problem

.ncb file contains information about VC++ Intellisense database.

You did not see the .suo file because you were using VC6.0

suo files are only there when you use VC2005 (or maybe already in 2003 but as I never used it, I cannot tell).

You should answer the OP directly. Also, the link you provided won't be very usefull for the OP because he uses VC6 (this article is about intellisense in VC2005).

Yea it may not be much useful to me ... but i can gain some information na...
