.net 2.0 framework not intalled error

3-Oct-06 1:54

Hello

You don't need to convert it to dll. You can read the output of the console in your C# application. See this post[^] on hot to do it. Don't forget to make the console hidden when it starts.

.Net framework 2.0 is must for the application builded upon it.

So, You have to install .net framework 2.0 on the every machine

to execute the application.

You should only need to install the .NET Framework 2.0 once on each machine. If you need to keep reinstalling it every time you run your application then there is something wrong with the machine.

It is recommended that Servers are kept patched and up-to-date. I wouldn't see it being a problem to state that your application requires Service Pack X in order to run.

Setting Treeview to another Treeview

I have a treeview and I want to set another treeview to that treeview

when I set TV1 = TV2 and do a breakpoint TV1 looks to have all the nodes, but it doesn't display. Does anyone know what I might have wrong.

Thanks.

Hello

TreeViews are reference types. That means that TV1 = TV2 will only copy the reference to the same object, but at the end they are still one thing. If you change anything in TV1, it will be also changed in TV2.

To copy the whole NodesCollection of one TreeView to another

TreeNode[] TV1Nodes = new TreeNode[TV1.Nodes.Count];
TV1.Nodes.CopyTo(TV1Nodes, 0);
foreach(TreeNode Tn in TV1Nodes)
    TV2.Nodes.Add(Tn);

Welcome to CodeProject! Big Grin | :-D

There is a very fine articles section here in CodeProject, with many articles for beginners. If you are stuck with something that you can't find in the articles -search first of course-, or google, you can always come here and ask.

Sure they are different languages despite the similarities. IMO C# is by far superior to VB, with all respect to all VB programmers and fans. Yet if you know VB, getting along with C# may not be that difficult. You just need to do you best.

forgive me if I read this wrong but he asked about C# vs VC#? I'm definitely a noob, is C# and VC# just the different names for the same language?

Maybe, he meant visual c#?

On what occassions would a form not recognize double click message?

I am pretty sure that is what he meant, but, is C# and Visual C# the same language? I think that's what he was asking and I'm curious as well.

One of my forms for some reason cannot use the mouse double click event. I know it's that form as another of my forms runs its DoubleClick(object sender, EventArgs e) fine when I double click it.

Here's what I did to my form: I made it double-buffered, set form border style to none, and gave it a background image. I also have several timers running on the form that randomly changes text on some of the controls. Could it be that too many timers (3 to be exact) on the form can nullify its doubleclick? What could be going on?

Hello

Nothing of what you did seems to make the problem. Are you sure you are clicking on the form itself, and not on a child control. Forgive the stupid question, but if you made your background as a Dock.Fill PictureBox for example, sure clicking it is different than clicking the form itself. Timers may downgrade your form's performance, but never to prevent event firing.

Are you sure that you registered the event, and nothing is unregistering it later using -=??
Are your timers going on very short intervals -eg. less than 5 milliseconds-?
Did you make a breakpoint to see if it's not actually firing, or are you assuming that becaue the code you wrote in the handler doesn't work?

Thanks, but it appears to be none of the above. Timer events no less than 200 milliseconds, i wouldn't know what could be unregistering it, The event really wasn't firing. I am also pretty sure I am not clicking on any of the controls on the form. But I forgot to include another thing. Because the form is borderless, i put in the following code taken from codeproject to be able to move the form. Could this be the cause? But it is strange because another form with this code works fine.

private void MyObj_MouseDown(object sender, MouseEventArgs e)
{
canMove = true;
x0=e.X;
y0=e.Y;
}

private void MyObj_MouseUp(object sender, MouseEventArgs e)
{
if(e.Button==MouseButtons.Left)
{
canMove = false;
}
}

protected virtual void MyObj_MouseMove(object sender, MouseEventArgs e)
{

if(e.Button==MouseButtons.Left)
{
this.Top+=e.Y-y0;
this.Left+=e.X-x0;
}
}

How to write a C# dll to be called in Delphi7

3-Oct-06 1:51

Umm... Non of the above should make the problem... In your Form_Load event try to register it manually again, and see if it fires then.

Hi,

I'm new to C#. Anyone know how can i create a C# dll which can be called by my delphi program?
What I did so far was create a new Class Library project. My codes are as below:

namespace MyTestDll<br />
{<br />
    public class MainTest<br />
    {<br />
       public MainTest()<br />
       {    <br />
       }<br />
<br />
        public void TestCall()<br />
        {<br />
           MessageBox.Show("Method is called");<br />
        }     <br />
    }<br />
}

It was then compiled as MyTestDll.dll
In Delphi, i tried using the usual LoadLibrary() and GetProcAddress() function to call TestCall function (in MyTestDll.dll), but it didn't work. Anyone can help me? Thanks!

Hello

.Net code -exe or dll- is not actually machine code as normal non .net compilers would generate. It's rather an IL -Intermediate Language- that is compiled JIT -Just In Time- in excution. So if you don't use Delphi .Net you won't be able to make calls to a managed .Net dll. Well, not directly.

I cannot use Delphi .Net as my current program is written in Delphi 7. How do i call it 'indirectly' then?

Nader Elshehabi2-Oct-06 19:07

2-Oct-06 19:07

One suggestion is to make you C# code another exe program, then communicate between the two programs some way. Example:
1- Make C# a console program and send your parameters as commandline arguments.
2- Make you C# a Windows service or a formless exe file and communicate using sockets for example.

Well, I hope this works! Otherwise you'd have to use C++ rather than C#.
