I'm very agrivated right now. I've created a worker thread that reads a file.. thats working perfectly. It parses and places all the data into an struct CArray. After that it checks for incomplete data. This is where things get screwy. It downloads a file perfectly (the function) in the thread with out crashing.
BUT
when I try to send the string that contains the missing data's URL it crashes. (See code)
CString CBookmarks::GetAllKeywords(LPVOID pParam)
{
//Declare Varables
//Date: 4 8 03
CBookmarks* pMain = static_cast<cbookmarks*>(pParam);
CCriticalSection m_cSection;
CString m_strAllKeywords;
int nSize=pMain->m_structBookmarks.GetUpperBound();
//
//DisplayItems
for (int i=0; i<=nSize;i++)
{
m_cSection.Lock();
m_strAllKeywords+=DownloadFile(pMain->m_structBookmarks[i].m_strURL);
m_cSection.Unlock();
m_strAllKeywords+=", "+pMain->m_structBookmarks.GetAt(i).m_strKeyword;
}
return m_strAllKeywords;
}
This crashes even when the debugger is running.
It reads the keywords from the first entry and then craps out when it repeats. The data in the next string is fine.
Even a TRY, CATCH_ALL doesn't catch it.
HELP!

Your locking looks odd. You have a lock declared as a local variable. This means that you aren't really locking anything since that routine has its own private lock. Also, if m_structBookmakrs is what you are trying to lock, then the GetUpperBound call isn't protected and could cause problems. That access should be locked too.

I did that and it still gives me a "runtime error" when I do that. Also when I try and debug it it doesn't give any information. When I don't use the loop varible i as the array number in the DownloadFiles function it returns the information perfecty, no matter how many times it runs in the loop.

Move m_cSection.Lock() and m_cSection.Unlock() outside the loop.

That didn't help. It still returned a Runtime Error.

Hi everyone,
I feel stupid, can anyone tell me the code for putting the check mark on a menu?

CWnd::CheckMenu or ::CheckMenu sound like they could be useful...

Hmmm...
Well, I just found the UpdateUI function, but it doesn't seem to do what it claims. I said pCmdUI->SetCheck(), but with no success. Didn't remove a check, or make one.
I tried something using the info that you gave me, but also with no success: GetDlgItem(IDM_SEND)->CheckMenu()... The compiler also didn't like this. Apparently, CheckMenu isn't a member of CWnd, which sounds ridiculus (due to the info you gave me).
Any other ideas?

CMenu::CheckMenu is probably what I meant to say...  
Are you sure your UpdateUI handler is actually being called? If you have a splitter window or something similar, it won't get called if the window is not focused.
You might also need to do something like this:
CMenu *pMenu = GetMenu();<br />
CMenu *pSubMenu = pMenu->GetSubMenu( ... );<br />
pSubMenu->CheckMenuItem( ... );
Look at the help for GetMenu, GetSubMenu and CheckMenuItem

Ok, that does it. Thanks!

How do I create an CArray of CArrays if I wanted to use a structure with some variables and a CArray embedded in it?
I have something like this:
struct STest
{
int IndexNumber;
CArray Data;
};
And then I made a CArray of this struct:
CArray <stest,stest&> FinalArray;
STest TempData;
Then I tried to Add with the FinalArray after loading the TempData with some data Ie:
FinalArray.Add(TempData);
When I compile I get a "operator =' function is unavailable" message.
What have I done wrong and what can I do to fix this?

STest needs to have an overloaded equals operator.
I recommend you make FinalArray an array of pointers to STest. Then you won't have to worry about it and you'll prevent a potential performance problem.

Since you are storing an array of objects, rather than an array of pointers, the objects will be copied into the array. This means that C++ uses the autogenerated assignment operator for STest. However, the CArray template class disables both the copy constructor and the assignment operator, therefore disabling simple copies of the array.
There are a number of solutions for this. Here's a few:
1) Store STest pointers in the outer array instead of objects. This means that only the pointers are copied rather than the entire object (and hence the inner CArray is not copied). This means that the objects must be allocated and deallocated manually on the heap.
2) Use std::vector instead of CArray. This is much better implementation overall, and does not have the copying limitation either.
BTW, when posting on codeproject, use < and > instead of < and >, otherwise they look like HTML tags and so are not displayed.

This is how you create a CArray that holds structures.
typedef struct {
int IndexNumber;
CArray Data;
} structName;
CArray<structname,structname&> m_caFinalArray;
Then to add data you must add it like this:
structName m_tempStruct;
m_tempStruct.IndexNumber=1000000000000000000; //whatever number you need
m_tempStruct.Data=blah; //more data
m_caFinalArray.Add(m_tempStruct);

So far i've set up a timer for 1000ms and each WM_TIMER event I capture the screen and save it to a BMP. If I wanted to record at 12 FPS how would I do this...?
Would I basically setup a counter and stop recording when it reaches 12?
How do I ensure I get 12 frames per second?
Also when playing the images back, how would I allow some frames to have differ delays?
p.s-If you know of any code on CP or wherever than would convert 24bit images to 8bit RLE encoded, please let me know...
Thanks.

You could set your timer to 83ms which would happen roughly 12 times per second.

Cool idea, I didn't even think of that...

Remember the WM_TIMER timer is not high-res - i.e. it is not guaranteed to fire exactly when it is set to fire.

Hi,
I have an ActiveX control and its dependend DLLs within a CAB file that we use within our web application. I also use this same control in a fat VC client. We currently deploy the control for our fat client by an install shield script. I'd like to get away from having to deploy this control, since I know it's sitting on a local web server in a cab file.
Is there an API set that allows me to reference the CAB file rather than bundling the control in my setup script? In other words, I'd like my fat client to instantiate the object via an http call to my web server and pull down the control rather than me having to wrap it in my install script. Any ideas appreciated.
