thanks, but that just replaces the text what is already there
what i need is
if my textbox contianed the following
"hello this is a test message"
if the user clicked into the textbox, and the cursor was then placed before "test message"
then clicked insert name, the text should read
"hello this is a Fred bloggs test message";

See my post from a little earlier. You need to use GetWindowText() to get the original text, put it in a CString, then use Insert() to insert the string you'd like. Then you use SetWindowText()

Is the text box an edit box? If so, you need to create a member variable for it. You have two choices, CString or CEdit. If it's a CString (e.g m_var) then,
CMyDialog::OnButton(){
UpdateData(TRUE);
int n = m_var.Insert(0, "Name to be inserted");
ASSERT(n == m_var.GetLength());
UpdateData(FALSE);
}So that when the button is pressed, the program gets the current text in the edit box, you insert the substring at the index indicated by the first argument to Insert() (in this example 0). UpdateData(FALSE) updates the dialog with the new text.
If you use CEdit, you can do something like,
CString temp;
m_var.GetWindowText(temp);
temp.Insert(0, "Name to be inserted");
m_var.SetWindowText(temp); And this should display the new text with the name inserted.

thanks danny,
I am using CEdit btw,
that will insert the text ok,but the text is always placed at the start of the sting, what i need is to place that text
where the cursor is positioned
hope that make sense

You need GetSel() to get the selection. Here's an example:
int startChar, endChar;
m_var.GetSel(&startChar, &endChar);
CString temp;
m_var.GetWindowText(temp);
temp.Insert(startChar, "Text to be inserted");
m_var.SetWindowText(temp);
} This will insert the text at the zero-based index indicated by startChar. Remember, the first argument to Insert() is where the text will be inserted.
Hope this helps!

You'll need to use CEdit::ReplaceSel() for this.

We've got an application i'm working on that utilizes COM Variants and Excel (values are read in from a text file and output into Excel).
Everything is hunky dory when the user is under US International Settings. However, when our European friends try out the product, there are some strange results - one of which i'm curious about here.
The process works like this: we read in some data, send it to Excel, read it back out (probably not the most efficient, but it handles some interpretation of the data we need rather effectively and my boss keeps me on a tight budget, so i just stick to what is quickest to do), format the data according to user specifications, and save it back into the Excel file.
The problem is what Excel says about international data when it is read back out - in particular, international numbers.
To demonstrate, here is what happens in the US:
Value: 1,000.00 -> Read in as a number in the VARIANT object -> Output to Excel correctly.
In Germany:
Value: 1.000,00 (notice the number formatting change) -> Read in as a BSTR(!) in the VARIANT object -> Output to Excel as text instead of a number.
i've monkied around setting my Regional settings to Germany, etc., but no luck. Any advice on this one? COM seems to want to stay whitebread American, and i'm having trouble broadening its horizons.
Thanks!

Please could someone help with the following:
I have a PC with 2 processors. I am writing two application in VC++.
I want one application to use CPU 1 and the other to use CPU 2.
How can I do this in code?
Please could someone post some sample code or point me in the right direction.
Really appreciate it.

I have no idea how to do this, but can only imagine that it would not be a good idea. In any case, the word you are looking for is affinity.

Hello,
I don't think that there is a way to say that your code should execute on a certain processor. The OS will arrange that (and I'm glad that it does  )
On VS2005 you can hint the compiler that certain parts of your code can execute on different CPU's simultaiously. Look here[^] for more information about OMP.

//I am working in VC 6. i have certificate file "FileStore.p7b" and able to

Unfortunately, my calls to AcquireCredentialsHandle always return
SEC_E_INTERNAL_ERROR. (I am using the UNISP_NAME package)
//to include private key info in my certificate context i used
CertSetCertificateContextProperty
//and set it CERT_PVK_FILE_PROP_ID ie., my private key is present in a

Can anyone tell me how to create a huge 2d array without affecting the processing time too much?
I used double pointer to create an array 2d array[27000][27000] as following:
BYTE **array;
array = (BYTE**)calloc(sizeof(BYTE*), 27000);
for (unsigned int index = 0; index < 27000; index)
array[index] = (BYTE*)calloc(sizeof(BYTE), 27000);
Right now, I need to increase the array size to 54000X54000 or even more. However, the compiler seems to have little problem to compile along with other codes. Even it compiles, the processing time is so slow.
Does anyone have a better way to profrom this task?
Thanks!

An array with nearly 3 billion elements? You need a 64 bit system to cope with that!

How much memory does your pc have? Your first array takes over 730MB so if you have less than 1GB of ram it will have to do some swapping which is 10 times slower than memory. Also the second array (54,000 X 54,000) is impossible on a 32 bit windows system as it is almost 3 GB.
Also Note:
There is a limit (because of the way dlls load) in a 32 bit windows program that is somewhere near 1.2GB. You may extend that if you create compile your program with the largeaddressaware switch turned on (google for details) and boot a capable operating system with the /3GB switch in your boot.ini file.

You probably dont need that big an array, depends on the kind of data that you will be working on.
May be you need to redesign your implementation so that it works on a small section of the array at a time and rest of the data goes in the array or maybe you need a database.

Look into CreateFileMapping/MapViewOfFile - it might allow you create big "arrays".

Thanks for all your inputs. The reason for such huge array is storing image information. In other words, 1 array cell equals to 1 pixel and also equals to 1 mil size (may go down to 0.5 mil per pixel). For a size of 54"X54" image, it requires 54000X54000 size of array.
With your expertises, there may be another way to work this out. In MFC, there is a CDC class in which have nice functions to draw on a bitmap. Creating such huge bitmap; however, is not possible. Is there a way to make this work? All I need is drawing some figures on a roster, and then retrieving cell by cell whether being occupied with a color or not.
I may ask too much but please help if you have some possible solutions.
Thanks

For such big array i would suggest doublly linked list. may be it complecates the stuffs but its worth. This will cosiderably improve performance.
If you can tell what for you r using this big array i can suggest.
Take it cool and just finish it.
