Nono, it's the opposite.
I don't need to make a delegate into an IntPtr, I need to basically make an IntPtr into a delegate.

Looks like a mixed-mode wrapper might be the answer. I haven't managed to get it to work yet, though (due to the PtrToStructure problem a few posts above).

Hi all,
I am building this GUI for a client I wrote some time back. I have done all the work on a Desktop machine in my office and it works fine. I have put it in a jumpdrive and tried still works fine (on the same machine). But when I bring it home and try it on my laptop, its has som weird problems.
My GUI has 2 dropdowns or the boxes called listboxes. When I run the program, these boxes are empty, they dont show me the items inside, tough they scroll and do take some random value from the list while excecuting. Is this some kind of property setting I am missing? Please do help me on this, as I am completed with everything else, and stuck here.

Hello,
I have a datagrid: dataGridRevenues.
and tablestyles : styleLotYields.
How can I access particular cells in my datagrid, and how can I raise an
event on leaving a particular cell.
Thank you

int currentGridRow = 0;
int currentGridColumn = 0;
this.dataGridRevenues.CurrentCellChanged += new EventHandler(this.OnGridCurrentCellChanged);
styleLotYields[0].TextBox.Leave = new EventHandler(this.CellLeave);
private void CellLeave(object sender, EventArgs e)
{
if ( this.currentGridRow == 9 && this.currentGridColumn == 2 )
{
//Do some stuff
}
}
private void OnGridCurrentCellChanged(object sender, EventArgs e)
{
DataGridCell dataGridCell = this.dataGridRevenues.CurrentCell;
this.currentGridRow = dataGridCell.RowNumber;
this.currentGridColumn = dataGridCell.ColumnNumber;
}

I'm not sure if this is the best forum for this, but I'll give it a shot. We have a large Win32 app (not MFC) - with many windows. We have developed many re-usable business-specific panels that we load into these windows at runtime based on a users configuration.
Now that we are moving to .Net and C#, it would be a big advantage to be able to create re-usable panels in C# and add them to our Win32-based framework. We have successfully done this before with ActiveX components - like the browser control for example. Basically we manage the activex control window's geometry in place within our Win32 window.
Would we be able to do something similar with a C# user control? Any ideas on how to proceed here?

You can use Interop to achieve this. tlbexp utility is the answer.
Please visit msdn.microsoft.com for the details. I have done this
successfully in my project.

Hello there!
I am trying to import data from excel spreadsheets to store it in datasets using OleDB, but something really weird is happenning for some cells.
What´s happening is that some cells (with non-null values)simply returns null.
Does anyone have any clue? Has someone experienced the same behaviour?
I would be thankful if someone could hel me with this issue.

You can try brute force...you can use the ExcelSheet.Range method/property to access the cell value.

I have a combobox that displays a list of dynamically loaded "plugin" objects, using the code below:
Assembly ControlLib = Assembly.LoadFrom( Location );<br />
<br />
object objPlugin = ControlLib.CreateInstance( ControlName );<br />
<br />
cboList.Items.Add( (IFTPlugin)objPlugin );
I have set the combobox "DisplayName" property to "Caption" (a member of the IFTPlugin interface), but it always calls ToString on the object instead and shows the assembly name instead of the friendly name.
I know that the object is loaded correctly, and that the "Caption" method is working, because I can call the following code and get the expected result:
string strCaption = ((IFTPlugin)objPlugin).Caption;
Rather than override the objects ToString function, is there a way to get the combobox to correctly call IFTPlugin.Caption ?
Thanks for your help.

Make sure to override "ToString()" method of the object you're adding to the dropdown. The dropdown will display the value returned by ToString and thus you dont need to set the databinding.
So ...
<br />
public class User<br />
{<br />
string _fname;<br />
string _lname;<br />
public User(string FName, string LName)<br />
{<br />
_fname = FName;<br />
_lname = LName;<br />
}<br />
public override string ToString()<br />
{<br />
return string.Format("{0}, {1}", _lname, _fname);<br />
}<br />
}<br />
<br />
private void form2_Load(object s, System.EventArgs e)<br />
{<br />
User[] arUsers = new User[2];<br />
arUsers[0] = new User("John","Smith");<br />
arUsers[1] = new User("Jane","Smith");<br />
this.comboBox1.Items.AddRange(arUsers);;<br />
}<br />
hope this helps.

There is one more twist to it.
Thoughts:
Make sure Caption is a property and has Get and Set implemented.

Hello, I have an interesting situation here.
I have a C# application called Aquisition.exe that uses a COM dll called reports.dll
The curioisty is that there are two versions of reports.dll - version 83 and version 103 and version 103 is registered on the machine.
Acqusition.exe 's manifest file refers however to version 83 - interop.reports.dll version 83. The interop.reports.dll refers to version 103 and it resides in the folder containing Acquisition.exe
There are no errors and it looks like version 103 is being used by Acquistion.exe even though its manifest refers to version 83.
Is this OK? Should there be a bug in the .NET CLR engine? Can I leave things be? Thanks for your thoughts.

Hi!
I need a file explorer to be able to implement it in my application, but they all those that I have found do not take the sight in Mosaic that one sees in Windows XP. There exists free someone that is capable of showing this sight? If not, is it possible to do someone? Better that I have found it is the Pi-Sys Labs's .NET Folder View (http://www.pisyslabs.com/DiskObserver.aspx) but it isn't free.
I think that it uses the explorer that show the OpenFileDialog, and show it as a control. How can be done that?
Thanks and sorry for my bad English

Hello,
Is there a way of placing a groove line on the Form? I tried to look
something up in Customization of a ToolBox, but to no avail.
Thank you.

hey Zaboboa,
To draw a line in c#, you need to use a label.
//
// label1
//
this.label1.BorderStyle = System.Windows.Forms.BorderStyle.Fixed3D;
this.label1.Location = new System.Drawing.Point(44, 68);
this.label1.Name = "label1";
this.label1.Size = new System.Drawing.Size(100, 2);
this.label1.TabIndex = 0;
this.label1.Text = "label1";
Or if you really want, you can make a user control that will draw the line(s).
K.
