Is there a c# version of this: http://www.codeproject.com/shell/shellextguide1.asp ?
Is it possible to do it in c#? Can anyone point me to a tutorial or even just briefly explain how to do it?
Thanks

In an old project we are using the Crystal report viewer (CrystalDecisions.Windows.Forms) which was orginally version 9.1.5000.0 but we have updated to version 10 now.
If I look at the properties of this referenced assembly within Visual Studio .NET it shows version 10.0.3300.0 but when we build the app and look at the assembly information on the .exe file it still shows version 9.1 begin referenced.
How to update the assembly reference?

Hi,
Can somebody please tell me how to use the "Item" property in System.Collections.SortedList class. I wanted to get and set the value field depending on the key.
Thanks
Raj

If you look at the documentation for the Items property, it says that it's the indexer in C# (the same as other lists' Items properties). This means you use it like this:
myList[key] = value;
value = myList[key]; You can use a key because a SortedList implement IDictionary, an interface for key/value collections. Mosts lists in the .NET FCL simply take an index (0-based, as with all .NET languages) in their indexer.

Thanks for your reply. I am new to .Net. Trying to understand these properties. DO I have to override this property.
I am doing like this, but it doesn't work. In my Sorted list keys are of type string and value is of type int.
public override int Item(string myKey)
{
get
{
return mySrotedList[myKey];
}
set
{
mySortedList[myKey] = value;
}
}
Thanks for your help and time.

Why are you trying to override this? If you're just using a SortedList, you just use it like the code example I gave. If you do want to extend a class, you only have to override abstract methods, and override other methods and properties as you need to. In this case, though, it's seems like you don't need to.
Besides, when you declare an indexer for a class in C#, you use the following syntax:
public object this[int index]
{
get { return internalList[index]; }
set { internalList[index] = value; }
}Read the .NET Framework SDK for more information, especially since your new. Specifically, see the Visual C# Language[^] topic.

I've played around with suspendlayout.
I believe it's there to stop changes to layout being applied before you have done all the changes that you need.
However, i've used the two following pieces of code, and they produce dramaticaly different effects in terms of rendering:
Code one: Low Flicker, Pretty neat solution
<br />
this.SuspendLayout();<br />
this.Size = new Size(newWidth,newHeight);<br />
this.Location = new Point(newXLoc, newYLoc); <br />
this.ResumeLayout(true);
Code two: High Flicker, massive jerking to either side of resize points.
<br />
this.SuspendLayout();<br />
this.Location = new Point(newXLoc, newYLoc);<br />
this.Size = new Size(newWidth,newHeight); <br />
this.ResumeLayout(true);
Any ideas why this is if they are only applied after ResumeLayout is run?

Read the documentation for SuspendLayout and ResumeLayout if you're wondering what they do. It pretty much states what you already suspect. If you have the documentation installed locally for VS.NET (and any decent developer should), it's a heck of a lot quicker than waiting for a reply.

I know what it does, but I was wondering why it displayed different behavior depending on layout if it was executed at the same time.
All i did was switch the two middle lines around, and it looks hideous.

I've got a C# application that connects to a database, and does various things with it. My question is this: When designing an application that uses a database, what is the best programming practices to ensure speed and reliability? Should I have just one dataset with many adapters, or multiple datasets and multiple adapters? Will having many adapters cause my form to take longer to load? I'm able to use these things fine, but I don't want an inefficient application in case I am doing something wrong. Thanks..
Also, I notice that if I set the source of a comboBox to a column in a table, that the comboBox takes the liberty of setting the text to the first item in that column. I've tried various things, like setting the comboBox.Text = "", or setting the selectedItem to -1. So far nothing has seemed to work...I want the comboBox text to start out empty...any suggestions?

The time to initialize a DataAdapter is negligible compared to the time to execute its Fill or Update methods which opens the connection and executes the appropriate commands based on the DiffGram (DataSet which change-tracking information). Set up your DataAdapters either upon initialization or use a provider pattern that initializes them only when needed (leaving the instances alive for future use).
Also, it's good to use typed DataSets. Typed columns refer to the columns in your tables directly, where referring to them by index - or worse, by name - requires several lookups. You can create typed DataSets in VS.NET by adding a new DataSet class to your project (Add->Add New Item) or using xsd.exe. The Solution Explorer can also help if you create a new DataSet class and drag-n-drop tables, views, or stored procs from a database connection to your design surface.
Finally, you really should read about the <cdoe>ComboBox.Text property. For one, it's only effective in some cases depending upon the value assigned to ComboBox.DropDownStyle. If you want to insert an empty element, after setting the DataSource property call Items.Insert(0, ""); or something similar. Take care, however, since this screw up your data binding (by inserting a null/empty column in your tables, which may violate a key constraint).

Doug:
I had the same problem with this in my program as far the the combobox is concerned. What i did was the following after a search.
dataset.Movie.Clear();
oleDbDataAdapter1.Fill(dataset);
if ( dataset.Movie.Count>0)
{
comboBox1.Text=dataset.Movie[0].Title;
}
else
{
comboBox1.Text="Sorry Jack No Data is in the Database!";
comboBox1.Enabled=false;
}
Hope this helps ya

I am using multiple projects and I am trying to add project refernece to another project and I get the following error message:
A reference to NDMUI could not be added. An assembly must have a "dll" extension in order to be referenced.
I have these AssemblyIfo.cs file and i tried to sign the assembly, but i didn't write the KeyFile atribute because i can't find the CPS that is installed on my machine. Could this be the problem??? Please help where you can.

Just like it says... Are you trying to add a reference to an .EXE file? If yes, then it won't work. Signing it won't help the situation...

As I mentioned to someone the other day, you CAN reference a .EXE if you use the command-line compilers. VS.NET won't let you, but the C# command-line compiler (csc.exe) and the CLR itself, for that matter, will. Don't ask me why VS.NET won't then - I wonder that myself.

I tried to use the C# command-line compiler, but the error message is still there.....what i actually was to compile my NDMUI.cs file.....i'm wondering if that is what you suggested??
|
|
|
|
|
Yeah, and what error message would that be? Do you tell your doctor that you have a pain and not tell him where?
You can reference a .EXE assembly using the /r switch just like you do a .DLL. I've done it before and there's nothing in the CIL specs that says you can't. A simple example:
csc.exe /t:exe /r:MyAsm.dll /r:MyApp.exe /out:Test.exe Test.cs Type /? as the switch to csc.exe for more information. If you get an error - which you didn't mention what error - still in your .cs source file, then it's something else. The error message will explain the problem.

I may have got thsi wrong, but are you trying to refrence an uncompiled CS file?
Q:What does the derived class in C# tell to it's parent?
A:All your base are belong to us!
|
|
|
|

No, the command line is compiling the Test.cs file, referencing two assemblies, MyAsm.dll and MyApp.exe. See the documentation for csc.exe in the .NET Framework SDK or type csc.exe /? for more information.
