From the description, you don't need an MDI app to do this.

I use Outlook and, no, I still have no idea what you want to do other than fill in the fields of a form. Why would you want to use an MDI form to do this?

You don't need an MDI form to do this. Among newbies, MDI is probably the second most abused idea, next to using a PictureBox to draw everything.
Make up your forms as normal. When you need to create a form and show it in the panel, you do something like this:
Dim currentForm As New BorrowBookForm()
currentForm.TopLevel = False
RightSidePanel.Controls.Add(currentForm)
You'll have to manage keeping only one form in that panel and destroying the previous form before putting the new one in the Panel. This is because if you don't, you'll run the system out of resources due to exhaustion of the handle pool.

I dont know how to create the property for TextAlign . NOt Coming with (System.Win.Forms.TextboxBase)
.Dim ctr as control --- TRhen i am getting properties butnot borderstyle,textalign ,etc
3) In PropertyGrid1_PropertyValueChanged , i am writing like this
Case "Font"<br />
ctr.Font = e.ChangedItem.Value<br />
Select Case e.ChangedItem.Label<br />
<br />
Case "BackColor"<br />
ctr.BackColor = e.ChangedItem.Value<br />
<br />
Case "BorderStyle"<br />
if ctype(sender,TextBox) then '''Borderstyle not coming <br />
ctr.BorderStyle( Not Coming) = e.ChangedItem.Value <br />

Hi,
I am not sure about your problem. If I create a form with a textbox and a PropertyGrid, all the textbox properties that you mentioned are in the grid. I see no issue.
Also what do you mean by "custom PropertyGrid" ?

Thanks a lot for your reply.I have read this tutorial and i am sure this will work work successfully but one problem is this tutorial is developed in .NET Framework 3.0 so how can do the list below:
1. Currently 1.1 is installed
2. I have downloaded 3.0 and installed it.
3. How can i switch to 3.0 without uninstalling 1.1
4. I am using visual studio 7.0

How can i get back column data from the dataset which i created.
The problem is that i have a table in the table second column i have some data but the table is in the dataset pl z tell me the technique how can i get it back.

A DataSet has a Tables collection. A Table has a Columns collection.
Use these to get the information you need.

Can any one help me to make a Attendance register that will record all Attandance of employees of my company. and on that basis i will generate the payroll. I have already tried a solution that will create Monthly Tables in Access example
Table name will be : EMPLOYEENAME/MONTH (ABC/FEB-07)
but this will be a lot space consuming. i want to try a diffrent solutions sample projects will be appreciated Please Help Guys.

This is a pretty straight forward task. Which bit are you worried about ? you want to create one table for all employees, and another that tracks attendance.

Okay - what it looks like you need to do is normalize your data.
This way you will keep space to a minimum and also keep duplication of data to a minimum.
So as an initial suggestion why not create two tables as follows(of course you will know the fields needed):
Employee table:
Employee ID
Employee name
address1
address2
address3
address4
address5
Tel no.
etc...
Attendance Table:
Employee ID
Date
Time start
Time End
Break time
You can then join the tables on the [Employee ID] field.
This is a start and you may need to add more tables/joins etc.
Hope this helps.
You always pass failure on the way to success.

Hello,
VS 2005
I have a typed dataset.
I am trying to fill the typed dataset from a datset that is returned from a web service.
<br />
Me.DsOrders.customers = ws.getCustomers()<br />
However, the error message I get is: "customer table is read-only"
Is there any way you can fill a typed dataset table like this. This works fine with a untyped dataset. However, I have already done this project using typed and too late to change now.
Many thanks for an suggestions.
Steve

I won't claim to be really sure, but I'm fairly sure that the error would be different if you did it the wrong way.
The error message is straightforward enough: the table you are trying to populate is read only at the moment you try to copy in the data.
You could just try to set DsOrders.ReadOnly to false, before you fill it.
Hope it helps,
Johan
My advice is free, and you may get what you paid for.

Now i succeed inject it to a process ,but the code in the dll dont execute

Which version again?? VB2 is REALLY old! Or are you talking about VB.NET 2002, or 2003, or 2005, or 2008??
yoya0303 wrote: Now i succeed inject it to a process ,but the code in the dll dont execute
VB6 does not support creating .DLL's of the type that are required to support "DLL Injection".
Also, just because you injected the code, doesn't mean that the .EXE knows how to call it. Your code has to hook something to be executed in the .EXE that you injected it into, or it has to be called from an outside source.

OK. I see what you're trying to do, but it's never going to work. VB 6 cannot generate the kind of DLL that is required for "DLL Injection". VB6 can only generate a COM-based DLL, which won't work for you because the required exports are not there. There is no way to "force" VB6 to generate those exports. You'd have to use some other wrapper around your DLL code to get this to work. Don't ask - I don't have any idea if someone has written one - let alone how to use whatever you find.

Thank you .I'll try to use C++ compile the dll.

For example i have a query table named (Qsupplier) consist of 3 rows and 5 columns.
EXAMPLE:
Supplier 1 2 3 4
Software Inc. 20000 90
Science Technology Co. Ltd 2000 800 500 80
Book Electronic Co. Ltd 30000 30000 24000 25
1. using the data reader how can i know if how many suppliers are there in the Qsupplier?
Thanks in advance guys.
