Do you mean to set a default value, or to get a value based on the tab that is selected ?

Use Tabcontrol_SelectedIndexChanged-event and whenever the tab with desired index is shown, reset your textboxes

i'm trying to display progress bar for file conversion of what percentage is completed, but the progress bar wouldn't display for vb.net but works fine for vb6. i'm updating our project from vb6 to vb.net, and i have problem displaying progress bar here is some code snippet.
<ProgressBar1 = New System.Windows.Forms.ProgressBar
ProgressBar1.Minimum = 0
ProgressBar1.Maximum = ItemsCount * 2
ProgressBar1.Value = 0
percentDone.Text = "0% Done"
CurrentComponent.Text = ""
percentDone.Visible = True
CurrentComponent.Visible = True
ProgressBar1.Visible = True
ProgressBar1.Value = ProgressBar1.Value + 1
percentDone.Text = Str(Int(ProgressBar1.Value *100_ ProgressBar1.Maximum)) & "% Done"
>
any help will be appreciated

It works. It's just that you're using the UI thread to do the file conversion. But, while the thread is busy running the conversion code, that code doesn't give up control of the thread so that the message pump code can run and process all the WM_PAINT messages that are stacking up in the windows message queue.
Move your conversion code to a seperate thread, try the BackgroundWorker class, and you'll be able to update the progressbar without any issues.

how can i give msge style withe specific fount and background color

I assume you are referring to the MessageBox dialog. The only way to change its appearance is to create a new form that looks like the MessageBox, just with extra controls to manipulate its appearance.

How can I change icon of any exe-file (example, "C:\1.exe") on my icon (example, "C:\1.ico")?? I am coding in Visual Basic NET. Please help.
|
|
|
|

You're talking about two different situations.
If you want to change the .EXE icon for an app you didn't write, you'll need a resource editing utility to do it.
If you're talking about changing icon in your own application at compile time, then you just need to go into the Project's Properties (Project menu, projectName Properties) and click on the Application tab. There's an Icon dropdown you can click on and select Browse in that list. You'll be able to pick an .ICO file you want with the appropriate icon image. If you want the greatest flexibilty, make sure your .ICO file has icon sizes in 16x16, 32x32, and 48x48, in both 16 and 256 colors.

Serial number?
Are you talking about the Primary Key (ID field) column you have on this table?? You do have a Pimrary key defined on this table, right?
In that case, all you have to do is specify it's column number in the SQL statement:
SELECT MyIdField, Name FROM MyTable WHERE expression
|
|
|
|

No sir,
i m not talking about Primary field. I just only want to attach "Serial Number" field with each row returned by query.
in primary key field, it is not essential that all records follow sequence because where clause is attach it
hope you understand my problem.

I still don't have any clue what you're talking about when you say "Serial Number". Is this is field in the database table already or something the database needs to generate or what??

sir, this is not a database field. I just want to generate serial number for each row returned by query.
let me explain. suppose i write following query
"select Letter from alphabet"
above query return all rows from alphabet table(but with single column). which is ---
Letter
a
b
c
d
.
.
.
z
but i want to result in following form without adding any additional field in database'table
S.No. Letter
1 a
2 b
3 c
4 d
. .
. .
. .
26 z
so how can i write query to generate this type of result

You can't do this without another field in the database. You MUST add a Primary key column, probably an autonumber, and that will give you your "serial number" for each row. When you execute a database query, unless you specify otherwise, rows are returned in whatever order the database sees fit at the time. There is no guaranteed order, therefor, any "math" you do to assign a serial number, which is going to end up being another column anyway in the DataTable, can be different for each row the next time you run the query.

Okay, I know how to zip a file, but is there a way to zip an entire folder?
|
|
|
|
|
It's the same as zipping a file. You just have to zip one file at a time into the same archive.
|
|
|
|
|
So, I just create a zip file called zip.zip, and just keep calling that same file in my zip function until I finish all of my files?
|
|
|
|
|
It depends on the library you're using, but yes, add one file at a time to the same .ZIP file.

I have an item called DashboardItem with inherits Windows.Forms.UserControl and declared the class as MustInhert :-
Public MustInherit Class DashBoardItem<br />
Inherits Windows.Forms.UserControl
I have then added some common features, such as a close button and title label.
The next step is to inherit DashboardItem into another class :-
Public Class VehicleTracking<br />
Inherits PDM.Session.DashBoardItem
The problem I have now is the designer reports :-
The designer must create an instance of type 'PDM.Session.DashBoardItem' but it cannot because the type is declared as abstract.
I need guidance on what to do to resolve this issue.
I checked out the MSDN Online help which was not very helpful at all, check out the description of the error message: http://msdn2.microsoft.com/en-gb/library/aa289354(VS.71).aspx[^]
Any help is appreciated
