Hi
From the main thread of my NFC based SDi application, i am creating a UI thread. Now from within the UI thread, i am creating a worker thread that does a very crucial job.
This worker thread has the tendancy to hang in certain situations.
To handle this hang sitaution, i wait on this worker thread from my UI thread for a max of 60 seconds using WaitForSingleObject(pThread->m_hTread, 60000).
Please have a look at the code snippet:
//This is a function in my UI thread.
BOOL CDocRecover::QuickRepair()
{
---
--- //some code goes here.
---
//Now here i am creating a worker thread.
CWinThread* pThread = AfxBeginThread(Worker_ThreadSample, wordDocs);
DWORD dwReturnValue = WaitForSingleObject(pThread->m_hThread, 60000);
if(dwReturnValue ==WAIT_TIMEOUT)
{
DWORD lpExitCode = 0;
GetExitCodeThread(pThread->m_hThread, &lpExitCode);
while(TerminateInstance(TRUE)==TRUE);
if(wordApp1.m_lpDispatch)
{
wordApp1.ReleaseDispatch();
wordApp1.Quit(covFalse, covTrue, covFalse);
DeleteFile(pApp->strTargetPath);
}
if(lpExitCode==STILL_ACTIVE)
AfxEndThread((UINT)lpExitCode);
}
int dp=0;
}
Now assuming that the worker thread has hanged, after waiting for 60 seconds the control will come inside the if(dwReturnValue ==WAIT_TIMEOUT) block & worker thread will be terminated after releasing some dispatch.
Now the problem is that after the call to AfxEndThread(), the control never reaches the line int dp=0;
I DONOT KNOW WHY?
The Application has not hanged but the control never returns to the UI thread.
Please suggest

is this "Worker_ThreadSample" function that you are using in afxbeginthread, a global function or a part of the class CDocRecover.
if it is a global function, then no problem.
have you tried to debug the application,
or have you tried by putting some messageboxes

Hi
Worker_ThreadSample(0 is a controlling function of the worker thread defined globally.
Waiting for suggestions

This is a poor design. If you start a worker thread, then immediately wait for
it to complete on the creating thread, then you've essentially gone out of your
way to create a single thread.
Regardless. does execution ever get to AfxEndThread()?

what could be done to get rid of link error 1181 cannot open input file d:\project.obj
|

to get your post clarified, you have to narrate the foreground and background of your problem and error.
you should also specify the platform in which you are getting this error.
|
|

You've instructed the linker to process the d:\project.obj file, which apparently does not exist. I suspect the d:\ path is invalid as most .obj files reside in a project's Debug or Release folder.

Hello to all,
i am a new one in MFC, right now in my project i am having a default ".rc" file lets say "a1.rc" which is created while generating the project.Now i want to create and add one more ".rc" file lets say "b1.rc" in my project along with "a1.rc",how to do it? i want to add one dialog box and some other resources in "b1.rc",how it can be done? also i want to generate new "resource.h" file for new "b1.rc" file so that "b1.rc" will not overwrite existing "resource.h" file for "a1.rc", how it can be done? how to give reference of this "b1.rc" file in my project? can any body help me please.
Thanks and Regards,
Anay Kulkarni

Hi anil,
There is only one resource file in a project and what u want, u can do it in existing resource file also. Go to Insert Menu -> resource (resource dialog box appear)than u may insert what u want and resource.h is automatically updated. 
Yes U Can ...If U Can ,Dream it , U can do it ...ICAN

what i under stood from his post is he might be looking to import one dialog box from another projects' rc file into his new project.
so he can open that rc file by importing it into his current workspace and copy paste the controls from the required dialog to the new dialog.
|

No Chandu,
he create one more .rc file in his worksapce. pls read his blog.He create one MFC workspace where .rc file is already created. now he want to generate one more rc file and according to my knowledge it is not possible.
Yes U Can ...If U Can ,Dream it , U can do it ...ICAN

yah shilpi, what you said is correct.
it is not possible to have two RC files in one project,
but now atleast iam unable to understand, why at all he requires two RC files in one project?

Unless something has changed over the years, you can just go in and include it manually in the existing ‘.rc’ file using ‘#include”, I think, just like a C or C++ header.
If you need to be sure how it is done, then just add an external file like a bitmap to your ‘.rc’ through the IDE and then open the ‘.rc’ (in text mode) to see what statement it added. Heck, come to think about it; that is all you should need to do to add an additional ‘.rc’ file within the existing file.
I once need to create the same version of an application with different logos and about information (sister companies) and it X was defined (for project) then X companies information would compile and show, otherwise company A’s information would show.

Anybody know how to get CPU temperature from the system.
what the function can support this issue.
Thanks
|
|
|
|
|
not all machines can support reading of the cpu temperature, it's a function of your BIOS software. Sometimes the bios manufacturer will supply dll's that you can reference to call the required function and return the details.

I am using a dynamic array that I often need to resize. I've tried a few way to resize it and so far this is what works. But their MUST be a better way.
Ideas?
int *n = NULL; // Pointer to int, initialize to nothing.
n = new int[2]; // allocate needed room
/////////////////////////////////////
/// Time to make more room!!
int *temp = NULL; //Create a temp 
temp = new temp[4]; //allocate
for(register int i=0; i<4; i++){ //transfer data to temp
temp[i] = n[i];
}
delete n; //delete old
n = new int[4]; //make new one
for(register int i=0; i<4; i++){ //transfer the data back
n[i] = temp[i];
}
delete temp; //delete temp
|

why don't you use vector<int> in this case you need not to worry about resizing it grows automatically
int the above question when you delete temp
write delete[] temp as it is an array the above code leads to memory leakage

I can barely begin to tell you what is wrong with that.
1) Use ‘vector’ and all your problems will go away.
2) If you must provided your own (do not double copy the data):
2.1) Allocate the new amount of space required.
2.2) Copy the old data to the new data space.
2.3) Free the old space.
2.4) Assign the pointer to the new space.
In C you would have another option (realloc) that if it failed, you would have to resort to (2) above, but I do not know a way to do that in C++.
P.S. delete[] n;
