Hi,
In which language are you writing the code for this? vb or vb.net? If in case of classic vb, use buttons as control array and write a single function. if in case of vb.net, write a event as follows :
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click, Button5.Click, Button4.Click, Button3.Click, Button2.Click<br />
Dim kBtn As Button<br />
kBtn = sender<br />
TextBox1.Text = kBtn.Text<br />
End Sub
Here you can use the source button's properties using kBtn variable.
Thanks,
Kiran Kumar

It seems to be that the result doesn't have a field named "ProfileName". Do you have such a field in the table?
Specify the fields that you want returned in the query, instead of using *. That makes debugging easier, plus it makes the query only fetch the data that you need.

That's what classes like List ( or ArrayList in .NET 1.0 and 1.1 ) are for.

Hi,
I need to disable a tabpage in a tabcontrol.
I 've tried to set the property "Enabled" to FALSE, but it doesn't shadow the text.
So I tried to set the forecolor property of the tabpage, but it doesn't work.
Finally I tried to draw each item by code as Microsoft suggests(through the drawitem event), but the result is really ugly (it losts the visual effects and the text doesn't fit in the bounds).
I cannot remove and re-add the pages for 2 reasons:
1) Each page could be enabled or disabled depending on several values in the form, so it is difficult to re-add the page in the right place
2) I LIKE the behaviour of old VB6 tabcontrol.
Can anyone help me ???
Thanx a lot.
Peace!
|
|
|
|
|
You two choices. One is to draw the tabs yourself, fixing your drawing code. I wish I had some examples to give you but I just about never use the TabControl, except in an Options dialog.
The other is to find a 3rd party TabControl that supports the visual effects you want. I don't know of any off the top of my head, well, because I just about never use the TabControl.

Hello
Try this that at the event of paint event of your tab page set its focus to some other or next object.
Example:
Private Sub tabpage1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles tabpage1.Paint
tabpage2.Selected = True
End Sub

Nice idea, the controls inside the page don't respond anymore.
This can be obtained (with grayed controls) also by setting the property enabled of the tabpage...
But doesn't resolve the problem of graying the tabpage title.
Thanks, anyway.
For other friends: the command is TabPage2.Select (is a method, not a property).

Advansis
Peace!

Hello. I need to activate a Timer control from other thread, so I think I have to use the Invoke method. As Timer don't have the InvokeRequired property as buttons and other controls, how can I do that?
Regards,
Diego F.
|
|
|
|
|
You create a method on your form that sets whatever you need on the Timer control. You can check the InvokeRequired of the form instead of the Timer control. Since the form's based Timer works on the UI thread, the Form is on the same UI thread and will tell you if InvokeRequired.
You Invoke the method you write from your other thread...

Hello,
I am working on VB.net form based application. I am having one user conrtol on the main form with some context menu item on it. All the handlers of these context menu items are implemented in the user control.
I want to implement all these context menu items on the main Menu of the main form. Now i want to call the same handlers of the context menu from my main menu.
How should i invoke the handlers form other class?
thanks in advance.

the handler in the control should be like this:
public overridable sub .....handler....
or
protected overridable sub .....handler....
and in the form u can call them like this:
public overrides sub ....handler....
...or u can make a public event in the control
...or make them all public and handle their events directly in your form

'Start Word and open the document template.
Set oWord = CreateObject("Word.Application")
oWord.Visible = True
Set oDoc = oWord.Documents.Add
oDoc.PageSetup.Orientation = wdOrientLandscape
oDoc.PageSetup.LeftMargin = 10
oDoc.PageSetup.RightMargin = 10
oDoc.PageSetup.TopMargin = 30
'Insert a paragraph at the beginning of the document.
Set oPara1 = oDoc.Content.Paragraphs.Add
oPara1.Range.Text = "Diamant Drilling Services Run Report"
oPara1.Range.Font.Name = "Arial Rounded MT Bold"
oPara1.Range.Font.Color = wdColorBlue
oPara1.Range.Font.Size = 28
oPara1.Range.Font.Bold = False
oPara1.Range.InsertParagraphAfter
oPara1.Range.InsertParagraphAfter
Set oPara1 = oDoc.Content.Paragraphs.Add
oPara1.Range.Text = "QDC"
oPara1.Range.Font.Name = "Arial"
oPara1.Range.Font.Color = wdColorBlue
oPara1.Range.Font.Size = 8
oPara1.Range.Font.Bold = True
Ok, there is the code that opens word, opens a new document and starts to insert some things into it. my problem begins with the last block of code. once it has written the word "QDC", how do i then write another word after it on the same line without overwriting the "QDC"
I am extracting info from a database and the recordset is going to be used to populate the document. So you will have the following senario:-
QDC TYPE NUMBER
SPH423 PDC S6L1543
the second line contains the data that is extracted from the database and has to be inserted under the relevent "column headings". there might be only one record or there might be over 200, depends on what the user has searched for.
Any ideas on how to do this guys?

Use the InsertAfter method. It'll move the insertion point to the end
of the insert text, ready for your next insertion. You can also use
TypeText but can't remember whether that moves the insertion point or not.
Some similar to...
Set oPara1 = oDoc.Content.Paragraphs.Add
oPara1.Selection.InsertAfter "QDC"

Hi! All,
I have to create CSV file using data of a table. Can anybody help me on this issue?
Thanks and Regards,
Virendra

You forgot to say VB6 this time. VB6 is a dead language, people will assume .NET unless you say otherwise.
Which bit can't you do ? Do you have the data from the table ? Do you know how to create a file ? If you broke this into it's three obvious parts and googled, I'm sure you'd find the help you need.

You can't, the aspx is processed before the code behind. Your best bet is probably a repeater, which means you have full control over what is rendered, and can better change it at runtime.
