What is "this" ?

Is "this" a TabControl ?

If yes, then use this.SelectedIndex = 1; (for example)

What is "this" ?

The this keyword refers to the current instance of the class.

My problem is how to reference the form from within a usercontrole placed on the form.

for example tabcontrol.SelectedIndex = 1; would not be able to escape the usercontrole subsequently it would not work because the tabcontrole is placed on the form not the usercontrole

Hope this makes my prob clearer !

Thanks once again for your time Smile | :)

Use the FindForm method.

I think it is only possible to do the reverse of what you want. i.e. You can make properties available at design and run time, or at run time only.

If i have mis-understood, u can use the browsable tag above the properties that you dont want to be able to see at design time.
e.g.

[Browsable(false)]
public string data
{
get { ect }
set { ect }
}

ComboBox, Lookup & Complex Binding

Hi,

I have spent all day on this and can't find the problem. Here's some code for a combobox that just won't show the name associated with the value passed to it:

[code]
this.comboBoxDefaultTitle.DataBindings.Add(new System.Windows.Forms.Binding("SelectedValue", this.newMemDefaultsBindingSource, "TitleNumber", true));
this.comboBoxDefaultTitle.DataSource = this.titlesBindingSource;
this.comboBoxDefaultTitle.DisplayMember = "TitleDesc";
this.comboBoxDefaultTitle.Font = new System.Drawing.Font("Microsoft Sans Serif", 8.25F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
this.comboBoxDefaultTitle.FormattingEnabled = true;
this.comboBoxDefaultTitle.Location = new System.Drawing.Point(50, 57);
this.comboBoxDefaultTitle.Name = "comboBoxDefaultTitle";
this.comboBoxDefaultTitle.Size = new System.Drawing.Size(151, 21);
this.comboBoxDefaultTitle.TabIndex = 1;
this.comboBoxDefaultTitle.ValueMember = "TitleNumber";
[/code]

I have done this before in the same project (different form and lookups) and they work fine. The above, plus two others on the same form and with similar tasks don't.

I've cross checked the relationships and compared them with the combobox that works and I just can't find what I've done wrong.

I've checked the msdn at http://msdn2.microsoft.com/en-us/library/3h6ac01k(d=ide).aspx and swear I've followed each step to the letter.

Can anyone please give me some suggestions as to where else I need to check to get this working.

Thanks,

Glen Harvy

After considerable searching on the internet I came accross someone with a similar (but not identical) problem that was resolved by someone pointing out that if a specified row in a datatable doesn't exist then the values shown to the user are those for the first row in the datatable.

What that means is that the datatable that is being looked up must be filled prior to the datatable that is being instantiated.

The wording above may not be right but the solution was to fill the newMemberDefaultsBindingSource AFTER the other binding sources had been filled.

Makes sense actually Big Grin | :-D

You can use also FileVersionInfo, see this example, just replace notepad with you messenger:

FileVersionInfo myFileVersionInfo = FileVersionInfo.GetVersionInfo(@"C:\WINNT\NOTEPAD.EXE");

string s = "File: " + myFileVersionInfo.FileDescription + '\n' +
	"Version number: " + myFileVersionInfo.FileVersion;

Console.WriteLine(s);

Thanks ..

Creating menu control+items via aconfig file(appsettings)

flackjack7-Aug-06 2:04

Hi I am rather new to C#, and I am starting a small windows application project for fun. I was wondering if it its possible to create a menu control with some items(eg. File, Edit) via a configuration file instead of using the designer view mode? How would i go about this?

I'm also wondering if it's possible to just create the menu strip control and items via designer mode, then edit the designer mode code to take in values through a config file?

Thanks Big Grin | :-D

You can always add MenuItems to a menu.

Something like this

foreach(XmlNode node in MEnuXML.SelectNodes(menu) )
{
MainMenu.AddItem( new MenuItem(node.value);
}

I think you would have to read the data in from the config file and create the menu items dynamically.

You could do this by creating an xml file for the config, then reading that in and creating the items to the list.

e.g.
// Read config file and serialize (sorry, dont have this bit 2 hand)

foreach(MenuData data in configFile)
{
MenuItem item = new MenuItem();
item.Text = data.Text;
mainMenu.MenuItems.Add(item);
}

Can anybody please tell me how the usage of RedirectBinding element can be utilised in App.config file. I want to redirect to newer version same assembly in GAC using App.config file, without recompiling the client application.

Thanks

Thanks senthil, but thats not working fine. My scenario is , I created two projects and refering one in another. I installed two versions of same assembly in GAC (a.dll 1.0 and 1.1). Now the reference assembly in project is a.dll 1.0. I added app.config file and added the redirection elements to redirect from 1.0 to 1.1

I executed the exe from bin folder where config file is also there. But the newer version assembly is not getting refernced at runtime, the same old one which i refered to project at design time is getting refered.

Any solution?

Use Itemtemplate columns. Columns that are editable user textbox, columns that are not editable user labels. When you are using item templates, itemdatabound even is mandatory, i am talking about web programming.
