Yes, us unmanaged developers are more productive since we don't waste time with meetings, explaining what we are doing to the project manager, or attending anti-productivity meetings

I use Visual c++ Net 2005
I have in my DataGridView one Column 'quantite'. In this column I need to put only numbers.
How can I format this column sothat I can only capture numbers ?

This kinda goes along with my answer to your previous question.[^]. There is no "DataGridViewMaskedTextBoxCell" available so you will need to get the cell that the user just modified and format/validate the value yourself.

if(e-->ColumnIndex==2)//Quantity

else

for float type variable :
bool bFloat = false;
int i = 0;
for each (wchar_t ch in e->FormattedValue->ToString()->Trim())
{
if(!wchar_t::IsDigit(ch))
{
if(ch=='.' && i == 0)
{
bFloat = false;
i++;
}
else
bFloat = true;

I am Using Visual c++ NEt 2005
On my form I have a DatagridView1 .
I Use it like a bill,I need, when I fill article code, to fill designation in a second column in the same line.
My problem is How to affect a value to a particular cell ?
To retrieve the content I know: dataGridView1[0,1]->Value->ToString. But To affect a value to a cell I don't know.
I need Help

You need to use the DataGridView.CellEndEdit Event. When the user is done editing the cell this event will fire and provide the cell location that was just edited. The link posted also has some sample code you can study.

I think you're looking in the wrong place. Just create a dll and dynamically link to it.

Is there any guidelines out there for which compiler option is best for Optimization? I have heard the minimizing size is important to reduce page faults but I'm not sure.
Opinions? links? Thanks

Yes on MSDN. However the significance of optimizations can be related to the version of the compiler, the OS, the hardware and more. So you are not likely to find any simple "Do this" answers.
Here is one as an example for VS2003[^]

I will recommend that you don't worry about optimization until you finish your application. Then you should profile your application and check which part(s) of code needs to be tweaked. This way you will save lots of time trying to optimized things which doesn't matter.

Wow - aren't you lost ?
The todolist is not written in Managed C++, and it has it's own forum for questions.

Hai
I am using textchange eventhandler in richtextbox. I just want to know currently what key is pressed by the user. for knowing that is any property is available.
can you tell me.
Thanks
|
|
|
|
|
if you want to get the key that was pressed you should use the KeyPress event. the second parameter (KeyPressEventArgs) you can use to get the keychar that was pressed.
Void richTextBox1_KeyPress(Object^ sender, KeyPressEventArgs^ e) {
char charPressed = (char)e->KeyChar;
}

hai
I just want to read the richtextbox content word by word.
Is any property is available in richtextbox. I am using windows form application vc++.
Thanks
|
|
|
|

i don't think there is a property that will give you the words. I think your going to have to parse the richtextbox yourself. You can get the words by doing this:
array<string^>^ words = myTxtBox->Text->Split(gcnew array<wchar_t> { ' ' }, StringSplitOptions::RemoveEmptyEntries);</wchar_t></string^>
you'll have to do more to trim out any punctuation characters.

Hi All,
I have created an unmanaged DLL, and them a managed wrapper DLL that permits to use, in other languages, the functions of the unmanaged one. Both the DLL's are made in C++.
I'm using the managed DLL to write a software, and since two days ago it worked all well. But now, when I try to run the application after compiling, the debugger says: SEHException on xxx.dll, that is the managed DLL. I tried to print a message box on screen for the stack trace, and the exception occurs when the managed DLL tries to call the unmanaged DLL.
Moreover, when I try to run it in another PC, it works perfectly 
I tried to search on Google but I didn't found any solution to this problem.
Can anyone help me?
Thanks in advance.
