OK - that's not the way I've added a reference for it.
Instead of going through the "COM" tab in the Add Reference dialog, try the ".NET" one, and if you scroll down you should find "Microsoft.Office.Interop.Outlook". Try using that as the reference instead.

Hello,
I have a ComboBox, which get its values from BindingSource, and gets its current value from another BindingSource. (If it matters, the source of the BindingSource is DataSet).
Here is the problem i am facing: i want the combo to present the values, but with exta information that changes from value to value.
I want that for strings that are 3 length long, will be showen with extra "!!", and strings with 5 length long will be shown with exta "@@".
For example, if this is the content of my DataSet (which connected to the BindingSource): dog, cat, cool, animal
so this is how the value would seem to the user:
dog!!, cat!!, cool, animal@@
of course i dont want the DataSet behind the BindingSource to be changed.. just for the combo presentation.
Thank you very much,
Liran.

This is how i did it"
i captured the event handler for FormatChanded.
and in it, i used the FormatEventArgs to change the value in code.
for example: if (blabla) then e.value += (blabla)
no CustomFormatter needed 
Thanks alot.

Actually, it's not crazy. It's probably something like :-
foreach (Object obj in myCollection)
{
myCollection.Add(anotherobj);
}
and it's telling you that you can't add / remove / clear or whatever in the collection you're iterating over.
If you only ever want to add new items, you can use a "for (int loop=0; loop<myCollection.Count; ++loop)", although that will iterate over the new items as well.
Otherwise, create "Add" and "Remove" lists which can be processed after the main loop to add and remove as needed.
There are three kinds of people in the world - those who can count and those who can't...

Sounds like Items was removed from your list before the line that causes error.
hope usefull.
sorry for bad english.

Basically, you cannot alter a collection of items as you ForEach over it. You can make changes to the items inside the collection, but you cannot add or delete items to the collection itself.

why does this happen?

I guess because the framework is keeping track of where you are in the collection, which assumes the collection will not change. If it does, what should foreach do ? you may have removed an item, how do you know if it has been iterated over ? Would you want it to be ? Easier just to say 'don't change this while I am working on it'. I suspect there's a more concrete reason than that, if you look into how it's implimented, but it seems obvious to me that it would create some situations where you could not predict the behaviour of foreach if you could alter the collection.

Hello,
I am writing a program that will be used in Labview (think of it as a scripting enviroment for those who do not know). I have about 30 dlls that are working together, some .net and some unmanaged. So I have a control in the labview that when it is run, the executable location becomes labview.exe in the national instruments folder. So the top dll is called, and then searches in the national instruments folder.
Then none of the other .net dlls can be called, because they are in the original folder.
So I want to tell the system where to search for my dlls. I found information about the config file and have been trying <probing> and <codebase> and nothing is working. Can you tell me what is wrong with my config file.
Thank you.
<code><?xml version="1.0"?>
<configuration>
<runtime>
<assemblyBinding
xmlns="urn:schemas-microsoft-com:asm.v1">
<probing privatePath="C:\Documents and Settings\admin\Desktop\csharp_core\bin\Debug\SubPlugs\" />
<dependentAssembly>
<assemblyIdentity name="PaintDotNet.Core" publicKeyToken="null" culture="neutral" />
<codeBase version="3.36.3426.17484" href="C:\Documents and Settings\admin\Desktop\csharp_core\bin\Debug\SubPlugs\PaintDotNet.Core.dll"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>

The privatePath is relative to the application's base directory and must be a subdirectory of the base directory.
Have you tried just
<probing privatePath="SubPlugs" />
Alan.

|

Hello,
Thanks for the reply. I did just try SubPlugs, but it did not work.
So I have
PaintDNetWindow.dll which is found
and then there is
PaintDotNet.Base.dll
PaintDotNet.Core.dll
PaintDotNet.Data.dll
...
which are called from paintdnetwindow.dll
The config file does not seem to be even read.
Thanks

Hi,
When you say "the" config file does not seem to be read it made me wonder if you have edited the correct one. i.e. the ????.vshost.exe.config or the ????.exe.config. I assume that the first is read during hosted debugging sessions and the second in any other situation.
Alan.
[EDITED: Sorry daft response. If you are editing the app.config file in the VS project then both config files would be updated.]

I'm creating a DataGridView at runtime.
Looking for the AutoSizeColumnMode setting which is usually available on the properties pane, but it does not show up as an option.
How can I resolve that?
Thanks

Hi.
Try this myDataGrid.AutoResizeColumns(DataGridViewAutoSizeColumnsMode.AllCells);

Thanks but "System.Windows.forms.DataGrid does not contain a definition for 'AutoResizeColumns'"...

You originally said that you had a DataGridView. The error message suggests that you have created a DataGrid.
Alan.
|
|
|
|

That's strange... I have just done it and it works...
DataGridView dgv = new DataGridView();
dgv.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells;
You haven't used 'DataGrid' by mistake have you?
Life goes very fast. Tomorrow, today is already yesterday.

Actually I did, thanks a lot!!

Make sure you're using the DataGridView control, not the DataGrid control. The DataGrid control was used in .NET 1.x and replaced in .NET 2.0 with the DataGridView control. The old DataGrid control is still in the ToolBox for backward compatibilty with the older control.

I need to change the default location that my application uses to reference files relatively. I use the syntax as follows: "..\\DBconnection.sec". This returns: C:\Projects\dotnet\RMS_IMCS\RMS_IMCS_WIN\bin\DBconnection.sec. I need the "bin" folder to be changed to RMS_IMCS.
my relative reference needs to look like this: "..\\RMS_IMCS\\RMS_IMCS_WIN\bin\DBconnection.sec".
This would allow me to chnage files located in folders outside my project without having to use absolute referencing. Any help?

I would highly recommend building a fully qualified path to the file. Using relative paths is problematic because the CurrentDirectory for you app can change without you knowing it. So, get the fully qualified path to your executable, then use the methods in the Path class to manipulate that path to give you the one you want.
