Ok, here's my problem:

I have a windows form program consisting of a parent MDI window and a series of MDI child forms within. Only one form is ever showing, and it is maximized.

On one of these forms, I have placed the AxWebBrowser control.

The first time I use Navigate to get to a URL, everything works great.

But if I then hide the form with the control and reshow it, the next time I Navigate the Web Control appears outside of the form in the upper left hand corner of the desktop (complete out of the MDI frame too).

Any idea what is going on? How can I avoid this?

Hi All,
I want the visual basic code to transfer the data from a VB application to the online application, similar to a text box in a website. I request you to email the code to tejassoft@yahoomail.com Smile | :)

If you want code written for you, go to www.RentACoder.com.

If you want help with your code, you've come to the right place. But you have to ask a specific question.

INI and CFG files

Help, I must be missing something simple

I declare (as I did in VB6) the following

Declare Function WritePrivateProfileString Lib "kernel32" Alias "WritePrivateProfileStringA" (ByVal lpApplicationName As String, ByVal lpKeyName As Object, ByVal lpString As String, ByVal lpFileName As String) As Integer

then I try to do this:

WritePrivateProfileString("test", "testKeyName", "AAA", "d:\temp\test.ini")

and I get this

Error "Object reference not set to an instance of an object"

any ideas are welcome...

Try defining it as such:

<DllImport("kernel32.dll", CharSet:=CharSet.Unicode, ExactSpelling:=False, CallingConvention:=CallingConvention.StdCall)> _
Private Shared Function WritePrivateProfileStringA(ByVal lpApplicationName As String, ByVal lpKeyName As Object, ByVal lpString As String, ByVal lpFileName As String) As integer
End Function

and see if that works for you.

Your Declare statement is wrong. Try changing it to:

Declare Function WritePrivateProfileString Lib "kernel32" Alias "WritePrivateProfileStringA" _
    (ByVal lpApplicationName As String, _
    ByVal lpKeyName As String, _
    ByVal lpString As String, _
    ByVal lpFileName As String) _
    As Integer

Select Text in a datagrid with one click

cruise9518-Oct-05 6:38

18-Oct-05 6:38

Hello all,

How do you select the text in a datagrid with one mouseDown? Like Microsoft Access lets you select text by clicking and dragging. I have only managed to do this on the second click (after the textbox has been selected).

My text box is read only, and I want the user to be able to select a portion of text in a cell after only one click and drag operation (not a click and then a click and drag).

I appreciate any help...

Hi everybody,This is my first Q in this informative forum.
I'm a new student in VB.NET'so would someone help me please?

I've a project in VB.NET ,where I've SQLData base connected to my project through ADO.NET components, and it's records displayed in Textboxes.
My first question is :
How can I add a button to search specific records determined by two columns in this DB ,and that must be by using one button.
for mor clarification:
when a user want to search the DB,s/he will have two choices according to two column chosen by this user , I and the name of these two columns e.g (patient'sName,patient'sNo)will appear whether on Checkbox or Radibutton and according to any choice the textboxes will represent the search parameters.
My project's code is under the namespace " System.Data.Oledb" .
My second question is :
What is the best technique uesed to make a connection to a DB in Vb.net, the ADO.NET(oledb) provided Data in VB.NET or using a code for each task and command? why?
I would be thankful for you.

Add a button. Add a handler. Write a stored proc that does the search based on the two fields. Call the stored proc, using the values of the text boxes, and show the result.

I'm not sure how you'd 'use a code for each task and command' ? Basically, the best thing to do is to create connections late, release them early. .NET has it's own connection pool. It works best if all your users log into the database with the same user/password ( so permissions are handled within the DB, not at login ).

Thanks Christian, but I tried many ways but I failed . Would you tell me please what is the code?
This is my form code:
B1 is to display the first record , B2 for the next one,B3 for the previous one& B4 for the last one. B8 is to make a search by one way,just by (PatientsNo),.So what is the code to make the search by two ways (patientsNo & PatientsName)?

Imports System.Data.OleDb

drobj = selcom.ExecuteReader

If drobj.Read Then
TextBox1.Text = drobj.GetValue(0)
TextBox2.Text = drobj.GetValue(1)
TextBox3.Text = drobj.GetValue(2)
TextBox4.Text = drobj.GetValue(3)
TextBox5.Text = drobj.GetValue(4)
TextBox6.Text = drobj.GetValue(5)
TextBox7.Text = drobj.GetValue(6)

Else
MsgBox(" The record isn't exist")
End If
OleDbConnection1.Close()
drobj.Close()
End Sub

Doesn't this work ? You don't need the brackets. Is PatientsNo a text field ? I assume not, but if it is, the string needs to be in quotes.

Help with building a SQL Query

Okie, I know this will be easy for someone to help with, since I have no clue what I am doing.

I have a DataAdapter linked to a datagrid. I have a textbox that when I type in a number, will bring up all those entries with that number. Everytime I try and edit the Query, I manage to mess it up. Any advice?

I am a Mechanical Engineering intern, but my boss got sent to Germany for a week, so they decided to put me with the Computer guys here, so they have me trying to program a website for them when I am not trained for any of it. hah sorry, little rant.

How can I display text on screen without showing the VB form? The form must be hidden and the text must be transparent but 100% visible. It must not disturb the user. It will be changing text just like the Subliminal Messages in "Self Help Subliminal" software. This needs to be done in VB 6.0 only.

Plz plz help me everybody. I shall be very very greatful to you people.
