I am pulling my hair out on why I am seeing different results in the VBA routines below. One method works perfectly (Internet Explorer code), the other (MSXML2.XMLHTTP code) does not work. I really...

Here is my TimestampDT() function;

Really weird, if I remove all the "pass though" varaibles created in the structure "ACC_MessageBox_Params" basically not using any of these variables [pParams->i] or [pParams->ACC_ErrorBuffer] the...

I fixed the code tags up, again sorry.

This memory leak is making me pull my hair out ... any ideas on why whenever this worker thread exists that immediately there is an increased use in memory?...

Sorry about the code tags, I will use them next time.

That is the way I had it when I started, I added the (LPCTSTR) for testing. The same affect happens with or without this (LPCTSTR) casting.

I have a memory leak whenever this code is executed, any ideas on what I am doing wrong?

{
int i;
CString ACC_ErrorBuffer;

Sorry, I am very new at C++ ... what is the "application class" and where is it located? Is "m_nNumber" the actual variable that would be shared between the routines?

Could you show me a code example of how to "keep this object as application class member" in order to make the variable available throughout all my routines? This is my first C++ project, I am...

I have an ofstream object declared as a global variable in my Dlg.cpp file, I'd like to close this ofstream when my "Close" button is selected in my AfxMessagebox routine which is on my main dialog...

I have attached my code for the sql worker thread. Please let me know if I am doing something out of the ordinary.

According to the specs on "Requery", this just closes and re-opens the recordset as well? Can you not leave the recordset open (without closing it first) and keep cycling through the updated fields?...

How do you access a SQL database's recordset within a "For" loop? I'd like to continually move through the recordset (using movenext and movefirst) without having to "Close" the recordset each time?...

Thank you very much for sharing these tips on C++! Since this has been my first project working with it, coming from VB, it does take some getting use to!

OReubens, I am trying to figure out what...

Is there any literature that you can recommend that deals with the proper C++ memory "structuring" you mentioned?

I feel I have absorbed quit a bit in a very short period of time in creating my...

I simply have 2 threads, sharing 6 variables (CString and ofstream), why is this so difficult? I should just stick with VB ....

Does anyone have any examples of a Modeless Messagebox? I tried...

I think I may revert back to a "Modeless Messagebox" and combine my thread1 and thread2. My only issue that lead me to try separate threads is because my messageboxes were stalling my single thread...

How do you get around timing issues between threads sharing variables? The code is scanning by so fast on one thread that it never gives the other thread a chance to exceute it's code, which is...

I added this code to cleanup should a unhandled exception occur;

=====================================================
void myterminate ()
{
exit(0); // forces abnormal termination
}

Do you have any example code to demonstrate such a Cleanup routine? How do you determine which objects need cleaning up? I could add "if" statements to see which mutex variables are still open and...

Thank you for all your feedback and patience with me, since I am new in this C++ field!

Arjay, I did skim through most of your articles, honestly, for a newbie it was a bit overwhelming. I did get...

I think I figured it out .... please let me know if I am out in left field on this one;


The code between the "lock.lock()" and "lock.unlock()" regions, is what gets executed, toggling between...

FYI,
I found this code on the web. My question is, where would the actual variables I will be using, be declared (i.e. the "ofstream" output file)?? How does the CMutex global object determine what...

Which method of synchronisation would be ideal for my application? I don't want to over complicate my code if it is not needed. Would using the "Semaphore" or "Mutex" method be my best option, or the...

My thread2 is strictly for handling communication with the SQL database. The values that are written/read by thread2, are copied into a global variable which is then, in turn, read/written by...

My SQL database updating routine is a simple read and copy to variable sequence. These variables are then read by my main routine. Would I need any sync'ing between these 2 threads, for the shared...
