Simple,
set form’s StartPosition property to CenterScreen
For your second question
Set form’s FormBoderStyle property to None and WindowState property to Maximized

Some XP user use the XP form style, some of them disable the style to use the classic one.
However, this style really affect the look of my form.
How can I know what is this setting in user computer?
|
|
|
|
|
You can P/Invoke UxTheme.dll which controls the window styles in XP like this...
<DllImport("UxTheme.dll", _
CallingConvention:=CallingConvention.Winapi, _
CharSet:=CharSet.Auto)> _
Private Shared Function IsThemeActive() As Boolean
End FunctionIf this function returns true, the user is running a theme, if it returns false then the user is running 'Windows Classic Style' - no themes.
Hope this helps
Cheers,

Thank you so much and It is really a great hint for me,
but it does not work by copy and paste.
Where should I place it in my module ?
Thank you~
|
|
|
|
|
To add it to a module you'll have to do two things...
1) Change the line
Private Shared Function IsThemeActive() As Boolean to
Public Function IsThemeActive() As Boolean (i.e. remove the word Shared and change the functions visibility to Public)
2) Add
Imports System.Runtime.InteropServices to the top of your file.
I havent done any VB.Net in a while so I hope that works
Cheers,
Will H

hi, i would like to insert a picture,(logo) of da company as a background and insert button ENTER on that.but i dont know how,sir, could u pls help me on doing that..thanx a lot.

You can specify a BackgroundImage for a form and place your buttons and other controls on the form as normal.
Other things that might be better for what you want are placing a PictureBox on the form with the logo in it. To make sure it stays behind the other controls, from the Format menu, choose Order > Send to back.
Or, place a Panel control on the form and set the Background image of it to your logo. You can then place controls on the Panel control itself (panels are container controls)
Hope that helps!

Hello!
This sample procedure extracts email addresses and adds to database. However, it is successfully adding the first address and creating empty records for the others. I decided to test the procedure with vb.net and took out adding the database section. It worked perfectly. So I would like to know what is causing not to add other emails except the first one.
Thank You
Sub AddEmails()
Dim GetEmails
Dim SrchKey
Dim xPos
Dim x1, x2
Dim xAddr
GetEmails = Request.Form("emails")
xPos = 1
x1=Instr(xpos,GetEmails,VbCrLf)
DO WHILE xpos <= len(Getemails)
x1=Instr(xPos,GetEmails,vbCrLf)
x2=Instr(xPos+1 ,GetEmails,vbCrLf)
If x1 = 0 or x2 = 0 Then Exit Do
If xPos = 1 Then
xAddr = Mid(GetEmails,1,x1-1)
Elseif xpos > 1 Then
xAddr = Mid(GetEmails, x1, x2 - x1)
End If
If len(xAddr) > 4 Then
'check here if email address is not exist in the database
SrchKey = "SELECT * FROM emails WHERE email="& "'" & xAddr & "';"
Call InitializeConnection()
Call Establish_Recording(SrchKey)
If ObjectRecord.RecordCount <= 0 Then
ObjectRecord.Close
ObjectConnection.Close
Set ObjectRecord = Nothing
Call InitializeConnection()
Call InitializeRecordSet("Emails")
'PROBLEM IS CAUSED BY THE FOLLOWING STATEMENTS
'IT IS ADDING THE FIRST ADDRESS BUT NOT THE OTHERS
ObjectRecord.AddNew
ObjectRecord("email") = xAddr
ObjectRecord("Accept") = True
ObjectRecord.update
ObjectRecord.Close
ObjectConnection.Close
Set ObjectRecord = Nothing
Else
ObjectConnection.Close
End If
xAddr = ""
xpos = x2
End If
LOOP
Response.Write ("Email have been added!")
Response.End
End Sub
|
|
|
|

This is just a guess. Wouldn't the ( xAddr="" ) set a blank each time the program made a loop?
|
|
|
|
|
Hello!
Thanks for your respond. Xaddr returns a value eact time in the loop. I have tested the code with vb.net. I think having connection to database or recordset inseide the loop is causing the problem even though connection is getting closed and object record set to nothing.

The picture box will move automatically if you set the control to anchor.
eg. picturebox.anchor = Bottom

Hi,
I have a question. How do you retrieve data from a textfile and have it displayed in VB. Net?
thanks for your help.
|
|
|
|
|
you can use IO.StreamReader(Server.MapPath("sms.txt")) to read ur text file.
or file open dialog box to open a file.

|

|

Server.MapPath is only for a web environment. For a windows forms app you would need to know the whole path.

Hi,
Does anyone know how to format a floppy disc without using DOS or Windows format windows. I am looking for code to format a floppy.

This is driving me mad. I have been working on windows forms application for a while and suddenly straight out of the blue the visual style for the buttons stopped working. That is, they go back to looking like buttons in Windows 2000. All other controls that support visual styles seem to be working ok.
Does anyone know anything about how to fix this? The really wired thing is that when I tried to do a new form in the same project all works ok for a few compilations and then the buttons just go back to ugly mode again.
By the way I’m using .Net 1.1 and visual studio 2003.
Regards Johan

I just found the solution to the problem, here it is:
Just after calling Application.EnableVisualStyles() call Application.DoEvents()

Hi,
I have a form where some selectioncriteria can be set. The form contains some comboboxes and also some datetimepicker's.
I want the following: when the form is loaded, I don't want any date to be shown in the datetimepicker's. Only when the user clicks the control, a date can be selected.
I tried:
dteFixDate.Value = Nothing , but this is not allowed.
dteFixDate.Text = "" , when the form is loaded, the current date shows in the control.
In fact, I want to use the values of the datetimepicker's in my SQL. So when no date is set (blank datetimepicker text), the date is not to be taken into account.
Does anyone know a way to do this. Or am I totally wrong in what I'm doing and is there an easier, cleaner way to obtain the result?
Thanks in advance,
