Creating listBox columns

Zones: Microsoft Visual C++.Net, Visual Studio .NET 2005

Tags: Visual Studio .Net 2005 - C++

Greetings:

I know it's possible to cause listBox21 below to show columns but I could use some help doing it.

My goal is to fill listBox21 with five columns that contain data from five objects in a queue. The string parameter 'strValue' will hold the string for one column. I'm hoping to be able to delete a particular column whenever the corresponding object in the queue is removed.

This would probably look nicer if it were done by rows but columns will work as long as I can reference the column in order to clear it out of listBox21.

So again, what code is necessary in the function below to enable me to create five columns or rows and delete the column/rows when needed?

Thanks

void Form1::ListBox21Msg(string strValue)
{

      Form1::listBox21->BeginUpdate();
      String *ListBox21Str = __gc new String(strValue.c_str());
      Form1::listBox21->Items->Add(ListBox21Str);
      Form1::listBox21->EndUpdate();
      return;
}

Hi John500,

in such cases I use CListCtrl instead of ListBox.
Did you think about that?

Andy

03.13.2008 at 01:25PM PDT, ID: 21120477

John500:

I'm not familiar with it but surely game. Can you show me how the current function would differ?

Thanks

bandyt1712:

Hmmm,
now I have a problem ... ;-)
Since I am writing C++ applications only, I am not quite good with VB.
I think, you may try to build a test application with a dialog and an ListCtrl
in this dialog. As far as I know you need only to drag the control in your form.
Then you should be able to see all possible properties and events in your IDE.

Sorry, hope that helps

Sorry, I mean .NET

John500:

Are you familar with the control - listView ?

I'm thinking this was the term I should have used in the question. I was using this about four years ago but remember having problems. I just finally found the code but still need help with it.

The code look like this:

Form1.cpp

void Form1::ListView1Msg(string strValue)
{
String StrMsg;

StrMsg = __gc new String(strValue.c_str());

Form1::listView1->BeginUpdate();
ListViewItem* item1 = new ListViewItem(StrMsg);
Form1::listView1->Items->Add(item1)
return;

}

Form1.h

Form1(void) {
...
public: static System::Windows::FormsListView * listView1;
public: static void ListViewMsg(string);
...
private: System::Void Form1_Load(System::Object * sender, System::EventArgs * e)
{
Form1::listView1->View = View::Details;
Form1::listVifew1->Columns->Add("", Form1::listView1->Width, HorizontalAlignment::Left);
...
...
}

John500:

I forgot about the .Net comment you added. I guess this means you are not familar, yes/no?

03.13.2008 at 02:16PM PDT, ID: 21120974

John500:

I recompiled this project and ran it but the poperties for this control within the designer don't indicate any kind of easy column creation. I get the impression it's all done by code.

bandyt1712:

Tomorrow I look at my source and send you a c++ sample, which you can adapt to .NET.
Unfortunately I can't access the source from home.

bandyt1712:

Hi John500,

the difference between C++ and C# is to big. So I think it is better to look at a c# example.
Hav a look at this:

Hope that helps.

John500:

Andy,

Thanks for the input.

The array was the answer:

for(i = 0;, i < 7; i++)
String ListViewArray[i] = __gc new String(DataArray[i]);

ListViewItem *ListViewData = new ListViewItem(ListViewArray);

Andy,

Here's another question concerning a list box if you get interested:
