Hi,
if i set Dockedproperty to none all controls are coming one behind the other.
|
|
|
|
|
Just set their Location.X and Location.Y properties and add them to whatever container your putting them in.
Dim myButton As New Button
myButton.Location = New Point(X, Y)
Me.Controls.Add(myButton)
Just be sure your not using the same X and Y values for the location.

p'' This is my code,
''y position is not same for all the controls.
Dim y As Integer = 0
If Dv_Tag.Tables(0).Rows.Count > 0 Then
For i As Int16 = 0 To Dv_Tag.Tables(0).Rows.Count - 1
CheckBox1 = New CheckBox
AddHandler CheckBox1.Click, AddressOf CheckBox1_Click
CheckBox1.Size = New System.Drawing.Size(150, 24)
CheckBox1.Location = New System.Drawing.Point(25, y + 28)
CheckBox1.SetBounds(25, y + 28, 150, 24)
Me.Controls.Add(CheckBox1)
Next
End If
End Sub

Where are you changing the value of y in this loop? Every iteration of this loop uses the exact same value of Y because you never change it. You might want to change your code a bit to do this.
For i As Int16 = 0 To Dv_Tag.Tables(0).Rows.Count - 1
CheckBox1 = New CheckBox
AddHandler CheckBox1.Click, AddressOf CheckBox1_Click
CheckBox1.Size = New System.Drawing.Size(150, 24)
y+=28
CheckBox1.Location = New System.Drawing.Point(25, y)
CheckBox1.SetBounds(25, y, 150, 24)
Me.Controls.Add(CheckBox1)

Hi I am trying to update record using this syntax,
SqlStr = "Update table1 SET table1.column_name =" & texbox.Text"
The problem is in the textbox, there is a quote in the middle of the string (') which VB cannot read. How do I convert that quote so that the vb can read the the sql string.

when passing the string try this
texbox.Text.Replace("'","''") <---
Dont worry it will store singe (') in the Database

VB can read the string without any problem. The real issue is that the method your using to build the SQL query isn't tolerant of characters that will create an invalid SQL statement. You'd be much better off building this as a parameterized query. You can read about what they are and why you should be using them in an article by Colin Angus Mackay, SQL Injection Attacks and Some Tips on How to Prevent Them[^].

Hi All,
Do any one know how to display a video clip in the form itself and not run it separately using VB .NET?
Please advice
Thanks
Best Regards

The simplest way to do this would be to add the "Windows Media Player" to your ToolBox, then drag and drop the control onto your form. You could then set it up to drop the user interface and then just tell it which file to play.
Player.uiMode[^] from the Windows Media Player 10 SDK docs.

hi there,
just simply close the form1 before showing form2

Can't do that. Since Form1 is his startup form, it'll close his entire application.

Search the articles here for Splash Screen. YOu'll come up with lots of examples on how to do it.
Basically, you can't make a splash screen your startup form. Closing it will close your entire application since you just shutdown your app's message pump. What you can do is launch two applications, the first being the Splash form and the second being your main form for your application. You'll see what I mean in the examples you find.
Now, for you login screen. You're main form has to check to see if it's login user ID and have been authenticated by whatever means your using. If not, your main form then puts up a login form that authenticates the user's credentials. Once the login form returns contorl to the main form, your main form then checks again to see if the login was sucessfull, and if so, just continues on it's way. If not, that's up to you. You can put up a warning that the user has limited functionality, or you could just quit, ...

Hello All! 
I have a problem regarding desktop application in vb.net...
Actually I have a formA that hasa a textbox...such that when the textbox gets the focus It calls FormB......
Problem is that when the formB is closed It gets the focus back to the textbox on FormA which in turns call FornB and so on...
i am making the FormB Model...
So my question is that is there any possibility that from FormB I can set the focus to any other control on FormA.......
It is to be noted that i am not closing FormA...
Thanx in Advance!

The problem is that you cannot set focus to a control that is not active and since FormA is not active at the time FormB is about to close (where you would want to set focus to another control on FormA) it can't be done. You'd also need to expose FormA's controls etc. to FormB to go down this path anyway and that is not a best practice.
What I suggest is that you set a global (to FormA) variable in the textbox's GotFocus() event before you show FormB and you conditionally show FormB only when this variable is False. This will prevent the infinite loop.

Thanx Steve.... I have already done this as you said by setting the global variable........
But I was thinking may be this can happen....
Anyways......Thanx
