Where are you adding this row? If it's in a dialog it has to be not before OnInitDialog.

I mainly use mc++ but can use standard c++ if needed. I am simply trying to get a consol to open and then open the cmd.exe process withing the consol window. I can only seem to open the consols in separate windows. I just need to send a string to the cmd.exe and have it execute the string and the prompt. Any suggestions? I have done multipal searches but they havent really helped. Thanks in advance.

What are you trying to do at the command prompt? Perhaps there is a better way.

You could do like this:
1. Create a console which you attach to the process using AttachConsole[^]
2. Run the commandline by passing it to CreateProcess[^] and give it your stdout handle which you can obtain from the GetStdHandle(STD_OUTPUT_HANDLE) function.
That should execute the commandline and output its output to the console window you created... But it wont give you a promt!
I hope I've given you some ideas...

Thanks for the suggestion. I'll give it a go. Looks like it will work well. Thanks. A friend of mine wants to play an old dos game that he just found in an old pile of software. It will not run correctly under XP. I located a file that fixes it but it needs to be loaded via cmd prompt and then the game must be launched via cmd prompt. It's easy to do manualy i just wanted to make a single exe that he could click and launch everything needed to run the game.

Ehm,...
Have you tried using a .bat file?
Or a regular shortcut?

Regular shortcut does not seem to work. Didn't try at .bat file. I am unfamiliar with .bat. Could you point me to a good resource? Thnaks

It's just a file which contains a number of commandlines that will be exeuted...
Try writing in notepad e.g.:
dir
pause
and save it to a file ending with .bat...

.bat did the trick, Thanks!

Hi,
I have created one class for thread and another class for HTTP client request and response both GET and POST methods. I have created 5 objects for thread and made the 5 client request for different web sites and I want to update response to text boxes or variables. I used SDK APIs (CreateThread). How do update the worker thread result to User interface controls.
Which is the best methods for multithreading mutiple client request?
Quote your thoughts...
Regards,

I usually accumulate the data in a data container class that has synchronization object protection. The worker thread writes data to the data ccumulator and then posts a message to the UI object when new data arrives. The UI object can retrieve the data from the data container class.
It is a best practice, to me, not to directly couple the UI object to the worker thread's activities - in other words, when data is ready, don't have the worker thread attempt to directly update the UI object.
You data accumulator can be a list or queue or stack or whatever makes sense for you to choose, and protect access to its data and operations with a critical section.

Hi there.
I want to create a dialog, with a menu ( file, help, edit etc.), and with tabs on the dialog. Basically like the display properties dialog that you get when you right click on your windows desktop, just with a menu added. Also, I want to add dialogs as the tabs, dialogs that I created separately.
Now if I use a CPropertySheet class, this allows me to add and display the dialogs, right? But how do I get a menu on the main dialog. And what if I want to add a button and a combobox on the main dialog, not on one of the tabs, but on the part of the main dialog that is not tabs.
Thanks for the help!!

The book The MFC Answer Book by Eugene Kain has simple instructions for adding a property sheet to a dialog (and then the dialog could hold other controls that are outside of the property sheet, one of your other points). The book VC++ MFC Extensions by Example by John Swanke has simple instructions for putting a menu in a dialog. I have found both of these books, as well as Swanke's Visual C++ MFC Programming by Example extremely helpful over the years. They contain many, many practical helpful things that you wish you knew how to do, on a wide variety of MFC subjects.
I'm sure that you could find instructions on the internet for these also with a little searching

i'm trying to get a IHTMLWindow2 object to use it's Scroll method. It's realy weird but it doesn't work. Here is the code i used.
m_pWebBrowser is IWebBrowser2* and has been corectly initialized...as in i can use it to control the IE window (Navigate...parse the source...).
[CODE]
HRESULT hr;
IDispatch* pHtmlDocDispatch = NULL;
IHTMLDocument2 * pHtmlDoc = NULL;
IHTMLWindow2 * p = NULL;
hr = m_pWebBrowser->get_Document (&pHtmlDocDispatch);
if (SUCCEEDED (hr) && (pHtmlDocDispatch != NULL))
{
hr = pHtmlDocDispatch->QueryInterface (IID_IHTMLDocument2, (LPVOID *) &pHtmlDoc);
if (SUCCEEDED (hr) && (pHtmlDoc != NULL))
{
pHtmlDoc->get_parentWindow(&p);
// this is were i get the error. p remains null
if(SUCCEEDED(hr) && p)
p->scrollTo(x,y);
}
}
[/CODE]
I realy hope some1 can help or at least give me an alternative way to scroll the IE window..other then sending keys.

Does anyone have any idea how I can load the images in a CImageList dynamically as the user scroll the list?
I need to do this becuase if the list contains many images (e.g privewing thumbnails of a dircetory with a lot of pictures in it) It consumes a lot of memory.
An example for such image thumbnail previewing can be found at:

IN MFC...
Plz guide me how can i apply a bmp on Tab control on all tabs including the upper tab label. Current application has bitmapped dialog box which is used in each tab but the label of tabs should also be bitmapped.

You have 2 options
1) You have to set the WS_OWNERDRAW style.
Check the MSDN library docs for ownerdrawn controls.
This allow you to draw the labels but not the empty space
where there are no labels.
So this option may not suit you at all.
2) If you want to customize the entire area of the tab, including borders,
you have to subclass the tab control and handle WM_PAINT yourself.
I strongly recommend this article that explains how to do this: http://www.codeproject.com/tabctrl/customtab.asp

I have a CListCtrl with 3 columns
I am using this function to know when someone clicks on the column button
void OnColumnclickList2(NMHDR* pNMHDR, LRESULT* pResult)
the problem is it is sorting the list according to the first column no matter what column button i press what sshould i do to make it sort according to the column button i press?
In other word how can i know which column button has been pressed?

Take a look at CListCtrl::SortItems[^]
If you pass both the list control pointer and a column index in some struct as the dwData parameter to SortItems, your compare function can obtain the text for the appropriate column and use it for the comparison.
struct SORT_DATA
{
CListCtrl* pList;
int nColumn;
}
static int CALLBACK
MyCompareProc(LPARAM lParam1, LPARAM lParam2, LPARAM lParamSort)
{
SORT_DATA* pData = (SORT_DATA*) lParamSort;
CListCtrl* pListCtrl = pData->pList;
int nColumn = pData->nColumn
CString strItem1 = pListCtrl->GetItemText(lParam1, nColumn);
CString strItem2 = pListCtrl->GetItemText(lParam2, nColumn);
return strcmp(strItem1, strItem2);
}
void CListCtrl_SortItems(CListCtrl* pList, int nColumn)
{
SORT_DATA data = {pList, nColumn};
pList->SortItems(&MyCompareProc, (LPARAM) &data);
}
You could easily extend this to allow for sorting order (ascending/descending), sort on multiple columns, etc.
Hope that helps,
