Can I use FOR EACH on an array of structures?

2-Jul-08 2:22

If I do this, I obtain what I need:

void OnKeyPress(System::Windows::Forms::KeyPressEventArgs^ e)override
{

if(!(wchar_t::IsDigit(e->KeyChar) || wchar_t::IsControl(e->KeyChar) ||(e->KeyChar=='.')))
e->Handled = true;
}

Thanks for you support

Hi, I'm using Visual Studio 2005 C++/CLI. I would like to access an array of structures using the for each construct. Is this possible?

ref struct TestStruct

};

array<teststruct^> ^teststructarray = gcnew array<teststruct^>(20);

for (int i = 0; i < 20; i++)
   teststructarray[i] = gcnew TestStruct();

for each (TestStruct ^teststruct in teststructarray)
{
   teststruct->i = 42;
}

value struct TestValStruct
{
   int i;
};

array<testvalstruct> ^testvalstructarray = gcnew array<testvalstruct>(20);
for each (TestValStruct %testvalstruct in testvalstructarray)
{
   testvalstruct.i = 42;
}

That's better Smile | :)

Can some one please point to a sample CLR project developed using VC++ .net 3.5 framework. Or a book which describes on creating projects in vs 2008.
Thanks

Everything you need to know is this (for VS 2008):

File -> New -> Project then look for Windows Form Application

click to Form1.h, you can see Form1.h [Design] and you can place some components from Toolbox there. In Properties are the characters of components.

Well I have not installed VS2008 yet but VS2005 and all the way back to like VC6 came with samples in the Installation. Take a look in your Programs Files/<VS install folder> etc., they may already be there, if not run the Installer and look for Samples as an option and install them.

Here's my short book on creating a CLR project in VS2008:

1) Start VS
2) From the file menu, choose New/Project...
3) In the New Project dialog, select .NET Framework 3.5 with the drop-button on the upper right.
4) Select Visual C++/CLR in the Project Types tree
5) Select a template in the Templates list
6) Give the project a name and location in the appropriate dialog fields, creating a solution if necessary
7) Click OK
8) Open the solution explorer window (View menu/Solution Explorer)
9) Right click the new project in the solution explorer and click Rebuild

You should now have a working sample CLR project developed using VC++ .net 3.5 framework.

Wow, I just saw this. Do you have a short book on toilet training also? Laugh | :laugh:

I mean if someone needs those instructions they have no reason to launch Visual Studio to start with. Wink | ;)

Hi. I'm using Visual Studio 2005 C++/CLI. I have setup my application to print a document (basically the screen). I had to set the e-Graphics->PageScale = 0.85 to get the screen to fit the page, but I need to have every page be of Landscape orientation. I have tried this->printDocument->PrinterSettings->DefaultPageSettings->Landscape = true and this->printDialog->PrinterSettings->DefaultPageSettings->Landscape = true (and some slight variations) but the document is always printed as set in the print dialog (which defaults to Landscape - Portrait). Is it because there are more than one printer on our network? Do I have to read the array list of InstalledPrinters and determine which one I am using and change the orientation that way?

Thanks,
Buck

Answer to my own question. It is this->printDocument->DefaultPageSettings->Landscape = true before calling the printDialog->ShowDialog();

Creating Playing window in VC++ Windows forms Applicaton

Dear All,

I am developing an application for decoding MPEG streams using DirectShow in VC++ Windows Application forms. Now I have connected all the pins of the filters after creating the graph. I want to run the graph, when I call pControl->Run(), a movie window will be created automatically and plays the movie. Instead of playing in automatically created window, I want to play the movie in the window created by me, bcoz I need to specify the size of the window and to have the full control of the playing window.

I have tried this in MFC and it is working fine by creating my own class and inheriting the CWnd class and using the CreateEX method to create the window. The problem is I dont know how to create the same window using VC++ Windows forms application. Please kindly advice.

Many thanks in advance.

No, I can't.

If you do some research (starting at that link), you'll see there's many methods
available for accessing databases from C++. Each has pros and cons.
Choose a method, learn how it works, then I can maybe help.

ADO.NET is probably the easiest to get started with in managed code, but
even explaining ADO.NET here is a bit much to ask.

You'll find tons of working sample code in the documentation.
