Igor,

I dont see any such property to reterive the get datagrid rows collection.
Is there any alternate way to reterive that.

First, what is the type of your datagrid ? Are you absolutely sure that this particular datagrid class have a method with the "get_DataGridRows" name ?

Hi ,

Am using windows form datagrid. The datagrid class has a private method named get_DataGridRows. This method will hold the DataRow collection of the datagrid. Since am inheriting the Datagrid class am not able to access this method. If i use it directly am able to access it.

Regards,
Kais

Windows Forms datagrid do have internal DataGridRows property and get_DataGridRows method is the get accessor for this property.

It's recomended to retrieve property value by obtaining a PropertyInfo object first and calling GetValue method on that object.

You must use Win32API to do that. Probably this is the right function:

Using Resource files .NET 2.0

Hi
I am just wondering how I would arrange things in a resource file. For example I want to add options under dropdown combo boxes in a resource file and read them from there - for doing this am i supposed to make a new resource file for each dropdown or add them in same one - but this way how do i identify which ones belong to which file.

If i add them as strings and give them names like Combobox1_Option1, Combobox1_Option2 .... and so on? then how do i get these out?

thanks for your help

Naming convention is totally up to you. I don't see a problem there!!

UnderWing wrote:

Using the ResourceReader class -but I assume you already know that- again I can't see your problem?!!

Please post more details concerning your problem, maybe I can help you then

Hints:
Why don't you add them all to one file and give them prefixes just like yoiu said??
Even why not put them in an XML file, or your app config file?? If it's not all about resources.

Problem with C# asp.net 2.0 TreeView [modified]

Hi

I am dynamically populating a TreeView using the method:
protected void TreeView1_TreeNodePopulate(object sender, TreeNodeEventArgs e)
{
}

but the problem is: e.Node.Parent is *ALWAYS* null even if I click on leaf and non root nodes! any idea why?? The ValuePath string is correct and the Depth property is also always correct but Parent will always be NULL! this has me totally stumped.

any ideas? I wasted like 2-3 hrs debugging other code for this but then finally found this to be the case and am using the ValuePath to determine the root node now Frown | :-(

(please reply here, do not send me an email thanks)

any help is grealy appreciated

Wrap your form and authentication mechanism into an assembly of its own. You can then reference that assembly from other projects. If it is well written it should be simple to do as there should be no dependencies for other parts of your original project.

Assistance with converting application to library

Hello, I've found an article on here that describes how to mask keyed in characters for inputting passwords:
ConsolePasswordInput[^]

At the bottom of this article it states that it's an application (obviously) but it can be easily converted into a library. I'd love to convert it into a library but I have no idea how to do this.

I'm relatively new to C#. I'm currently running MS Visual Studio 2005 with .Net Framework 2.0

I was thinking I could start a new Class Library project and just paste in the required code, but I believe that will create a .dll file. I believe that once my application makes use of this library it will have to register itself, and I was trying to avoid having my application register anything.

If anyone is able to help or even just point me in the right direction, I would greatly appreciate it. Please let me know if you need anymore information!

A Class Library project will produce a DLL. By registering, I assume you're talking about registering the DLL to the GAC... Which isn't necessary. You can create a new class library project, and paste in the necessary code. Then have your application reference that DLL (or project if you have both projects in the same solution) to use the classes in the library.

If you don't want to do that, you can paste the necessary code into your application's project instead, which will work just the same, it just won't be usable by other projects.

Does that help?

You are correct that it would create a .dll. You dont have to register it, however, unless you want to, but is usually unnecessary unless you plan on a lot of apps accessing it. Just compile the dll and add a reference to it in your projects. It will be copied and distributed with your app (in the app folder) without registering.

If you do decide to register your dll, just create a strong name with the sn.exe utility (from the .NET SDK command prompt) to create a key pair, then assign that to your [assembly:KeyName] attribute of the .dll (assemblyInfo.cs/vb). Then recompile and use gacutil.exe (.NET SDK command prompt) to register the dll in the GAC. Only do this if it is absolutely necessary, however.

HTH.

ListViewItem color issues

Aaron Dilliard3-Jul-06 8:31

On many of my applications I make use of a ListView control, that has a certain color displayed on the column that is currently sorted. It also highlights rows for special things. In .NET 1.1 this worked perfectly, but whenever I try to import an app into .NET 2.0 (VS 2005) the color highlights only show up when the form loses focus and gets it back. If you scroll, the items lose the color. This also happens when the SelectedIndex changes and the highlight is given to a new row. The previously selected row loses color. As I said before, the only way to get back the color is for the form to lose focus and regain it. Is the ListView drawn differently in .NET 2.0? Anyone else had this issue? Thanks in advance

I don't think there are any major changes that would break an app.

Aaron Dilliard wrote:

Nope

My guess is that you're not handling it as well as you could be. Are you deriving from the ListView control and overriding the OnDrawItem method or are you handling the events. If you're handling the events I'd try overriding the method in a custom control.

Sorry I'm not of any further help

I agree that there are no major changes that would break an app, but even subtle changes in the way the control is drawn could have an effect on 1.1 code. IE, if a WM_PRINT message is sent with the ERASEBACKGROUND flag or something like that, that could be the culprit. I know Microsoft changed the control some in 2.0, and Ill bet that is what is going on. I will just have to rework the code. Thanks for the input.

Keeping the summery after compilation...

I have a dll I wrote.
It contains comments and summaries (XML summaries if I'm not mistaken)...

After compiling the dll, and referencing it in another project, summaries are never shown...
Is it possible not to lose them after compiling the dll?
How exactly?

Thanks,
Shy.

XML comments are never included in the compiled assembly. If you want to see your comments as hints in another project complie your dll with /doc directive (or set "XML documentation file" project property). And always keep generated xml-file close to your dll.

Hello

If you mean the ///summary block the precedes methods and properties, then the problem would be in your syntax because it should appear as a tooltip when you try to use the methods of your referenced dll.

Post an example of a method's signature that your wrote with its summary, maybe we can come up with something.

Regards Rose | [Rose]

Andrew Lygin3-Jul-06 18:59

It should appear only when dll and client application are in one solution. Comments are not metadata and compiled assembly doesn't contain them. So none can show these comments as tooltips (even VS Wink | ;)

).

To see the problem just create a simple dll and then make reference on it from another solution. You won't see your XML-comments in tooltips until you generate xml-file with /doc for your dll.

For more information see this article in MSDN Magazine.

Selected index on fully editable grid/merging datasets

leckey3-Jul-06 7:08

leckey

3-Jul-06 7:08

I asked this question before and was referred to a CP article, but I posted another follow-up question and didn't hear anything.

Part 1:
I have a datagrid. I know how to populate the drop-down box with "Part Types." What I want to do is a) If there is an existing record, highlight the PartType saved in the database, or b) if this is a new record, just list the first alphabetical PartType choice.

So I created a function GetDescriptions which I call from my ASP page like thus:
asp:DropDownList ID="test" Runat="server" DataSource = '<%# GetPartDescriptions()%>' DataTextField = "Description"

And here is the function:

public object GetPartDescriptions()<br />
		{<br />
			string SQLString = "SELECT Id, Description FROM PartTypes ORDER by Description";<br />
			SqlCommand cmd= new SqlCommand();<br />
			cmd.Connection = new SqlConnection(strConnectSQL);<br />
			cmd.CommandText = SQLString;<br />
			SqlDataAdapter adapter = new SqlDataAdapter(cmd);<br />
			DataSet ds = new DataSet();<br />
			adapter.Fill(ds);<br />
			return ds;<br />
		}

My grid is already editable when they enter the program. So how do I set the index for existing records?

Part 2: I did the function as a separate dataset. (If there is a better way please let me know.) I need to merge this with the original dataset (the main grid of partnumber and stuff). I know I can use the merge method.

What I really want to do is merge the individual record in PartType to the main dataset. Not the entire PartType collection. Can this be done with merge?

THANK YOU THANK YOU!

Hi,
I currently use visual web developer 2005.

I would like to know how to link from code behind file to the constructor file (set get) inside the App_Code folder

Is there anything I have to import?

I try to set the value into the class file, and get it, after compile no error, but no value returned back....

example:
in .cs file
-----------
String strName= "Baby";

SetProperty sp = new SetProperty();
sp.Name = strName;
String testing = sp.Name;
Trace.Warn(testing+ "this is testing"); // no value returned...

in SetProperty.cs (inside App_Code folder)
--------------------------------------------
public class SetProperty
{
private string strName;
public string Name {
set{ strName= value;}
get{ return strName;}
}
}

Help, ps point me to the correct direction.. thanks.
