Thanks your help.
array<label^>^ myLabelArray = gcnew array<label^>(10); //Its work But
myLabelArray[0]->Location = Point(100,100); //NOT WORK

Hi,
maybe my first statement lead you in the wrong direction.
array<Label^>^ myLabelArray = gcnew array<Label^>(10);
This line just creates an array with 10 references of the type Label.
A reference type is implicitly initialized with a nullptr, thus myLabelArray[0]->Location = Point(100,100); will not work unless you initialize it first.
// will work
lab[0] = gcnew Label();
lab[0]->Location = Point(10,10);
You should also use try-catch to catch exceptions that possibly occur.
regards Tobias

No Error Occur But I Can't See Label on the Form
array<label^>^ myLabelArray = gcnew array<label^>(10);
myLabelArray[0] = gcnew Label();
myLabelArray[0]->AutoSize = true;
myLabelArray[0]->Location = System::Drawing::Point(100, 10);
myLabelArray[0]->Name = L"lblX";
myLabelArray[0]->Size = System::Drawing::Size(63, 13);
myLabelArray[0]->Text = "HELLO";
myLabelArray[0]->TabIndex = 50;

Hi,
you forgot to add the label to the form.
private: System::Void Form1_Load(System::Object^ sender, System::EventArgs^ e) {
array<Label^>^ myLabelArray = gcnew array<Label^>(10);
myLabelArray[0] = gcnew Label();
myLabelArray[0]->AutoSize = true;
myLabelArray[0]->Location = System::Drawing::Point(100, 10);
myLabelArray[0]->Name = L"lblX";
myLabelArray[0]->Size = System::Drawing::Size(63, 13);
myLabelArray[0]->Text = "HELLO";
myLabelArray[0]->TabIndex = 50;
myLabelArray[0]->Visible = true;
this->Controls->Add(myLabelArray[0]);
}
};
regards Tobias

It's work, thanks a lot 2bee...

I am not sure if I am posting in the right area, but I am looking for STI resources. I heard that WIA is just a wrapper for STI, however WIA 2.0 doesn't work with older Windows versions. Any C++/C/C# or other .NET supported language resources for STI is what I am seeking. Thanks a lot.
I love to program!

What are STI and WIA?

STI is still image architecture. It's a way to access digital cameras. WIA is Windows Image Acquisition. It's also another way to access digital cameras. My problem is WIA doesn't work on all operating systems where as TWAIN and STI will. I just need a way to access a digital camera on most operating systems (Windows 98 and above). Also, the digital camera does not mount as a drive or this would be a simple matter.
I love to program!

The following was posted to the .NET foram, but few questions seem to be answered there.
I am no longer mad (upset) just tired. Being .NET seems to go automatically with managed, but one thing at a time.
**
This is driving me nuts! 
I am writing my first C++ .NET application and all I want to do is load a bitmap resource. Normally I would do something like ::LoadImage(IDB_BITMAP), but it says it is not in the global namespace. I want to load it as an Image type, but Image only has method for loading from a file or via a windows handle.
The code should look something like the following:
pImage->FromResource(IDB_BITMAP);ORpImage = resources->GetObject(IDB_BITMAP);
This should be simple!
Thanks for any help,
INTP

Hello,
i found this article quite useful and it could help you in solving your issue.
However this article shows how to create resources (bitmaps etc.) and use them within a .Net program. I am not quite sure if this is actually what you want. Furthermore it is written in C# but on the other side, C# is easy to convert to C++/CLI.
http://www.jelovic.com/articles/resources_in_visual_studio.htm[^]
so it would be instead:
ResourceManager^ resourceManager = gcnew ResourceManager("MyCompany.MyProject.SomeResources", GetType().Assembly);
Bitmap^ image = (Bitmap^)resourceManager->GetObject ("MyBitmapName");
Hope this helps,
best regards Tobias

Thank you very much! I do not know if it will help or not (yet), it looks very simular to what I have been tryiing to do. If it is written in C# I can not tell the difference, becuase it looks exactly the same as in C++. If .NET is what the next generation of progammers is going to have to learn, then I feel sorry for them. Actually I should not, since I am now going back to school. But they are making us write everything in vb.net, all pre-packaged stuff (controls, etc...). If I was not tryiing to use .NET and managed code the program would be all but finished by now.
Thanks again,
INTP

Hi,
I have installed Visual Studio 2003 and .net framework 2.0.
How can I use .net framework2.0 Toolbox in Design mode?
I only see .net framework1.1 components in Toolbox.
|
|
|
|
|
VS 2003 is incompatible with .NET 2
You need VS 2005.

hey all,
I am trying to make a program to turn off my computer on a set timer, for when i am burning dvd or listening ot music before bed. Can anyone help me withthe c code to shutdown a computer through a c program.
i know through the command prompt there is a shutdown command:
/shutdown -s
with a [-t XX] XX being the time before the shutdown.
so if there is a way to make my c program use the command prompt, or another way to shutdown the computer, it would be greatly appricated.
Thank you Very much.

In C, you could use a Wind32 call:
CreateProcess("shutdown.exe", "-s -f -t 00", NULL, ...);
For more detail, check MSDN
For other methods, check CodeProject.
- It's easier to make than to correct a mistake.

Will i need to include any special header files to use that command.
thank you/.

I think you need
#include "Windows.h"
- It's easier to make than to correct a mistake.

Thank you very very much Jun Du, i did not use the CreateProcess method but i used theother method which you provided the link for me. For anyone else trying to do this, here the code i used:
#include <windows.h>
#include <shellapi.h>
Main() {
ShellExecute(NULL,"open","Shutdown","-s -f -t 30", "", SW_SHOW);
return();
}
Thank you Jun Du.

Systematic specification
Introduction
Read into the materials by the file and preserved parking
While parking (order P)
Input the number plate number of the automobile
The record parks on date and time
Write down the corresponding relation of the serial number of parking stall and automobile number plate number

is there anything other than #include "stdafx.h" that I need to include in order for me to do:
MessageBox::Show("Hello, World!"); ?
i'm getting the following errors:
c:\documents and settings\...\mda_camera.cpp(40) : error C2653: 'MessageBoxA' : is not a class or namespace name
c:\documents and settings\...\mda_camera.cpp(40) : error C3861: 'Show': identifier not found
Thanks

Managed C++ questions have to be asked in the Managed C++ forum 
after another read of your post, it seems that you use some managed code in your MFC project.
change for the following :
::AfxMessageBox(_T("Hello Wolrd !"));

If you need to ask this, I am not sure you need to be using Windows Forms.
