I am working on a project called Image Editor.
Now I am in beginning stage
It has three forms
1. Image Editor (MDI Form1, ismdi container=true)
2. Image (Form2) 3.Resolution (Form3)
I have added a Menu bar and there is File Menu on it.
File Menu has five submenus as following
1. New (opens a new window)
2. Open (open the image)
3. Save (saves the image)
4. Close (closes the active window)
5. Exit (exits the main application)
I want to do some changes in it, these are follows
1. When I click on new there should be dialogue appear (Resolution Form)
In it I can set height and width of form and then I click on OK,new window should open according to these setting. And the caption of new form (image form) should change as Image1,image2 and so on.
2. When I click on open it should load the image into the form (Image Form) what resolution image has.
It should load the form in active window(i.e. image1).If there is no open window already then it should load the image in new window(i.e. Image1).If there is new window already(i.e. image1,image2) but non of them is active then it should also open a new window and load the image in it.(i.e. Image1,image2)
3. When I click on close menu, it should close the active window .for example image1 window.
Also I have added a Panel on the Image Form and set it dock property to fill.
And I have added a Picture Box and I have loaded a Picture through property box.
Now my code can scroll and pan an image on the form.
My Code till now as follow
VB.Net 2005
Public Class ImageForm
Private m_PanStartPoint As New Point
Private Sub ImageForm_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'Panel Settings
Panel1.AutoScroll = True
'Picture Box Settings
pb1.SizeMode = PictureBoxSizeMode.AutoSize
End Sub
Private Sub pb1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles pb1.MouseDown
'Capture the initial point
m_PanStartPoint = New Point(e.X, e.Y)
End Sub
Private Sub pb1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles pb1.MouseMove
'Verify Left Button is pressed while the mouse is moving
If e.Button = Windows.Forms.MouseButtons.Left Then
'Here we get the change in coordinates.
Dim DeltaX As Integer = (m_PanStartPoint.X - e.X)
Dim DeltaY As Integer = (m_PanStartPoint.Y - e.Y)
'Then we set the new autoscroll position.
'ALWAYS pass positive integers to the panels autoScrollPosition method
Panel1.AutoScrollPosition = New Drawing.Point((DeltaX - Panel1.AutoScrollPosition.X), (DeltaY - Panel1.AutoScrollPosition.Y))
End If
End Sub
End Class

Code is according to vb.net2005

So create a form that asks for this information. If your code that starts creating a new document, create a new instance of this form and show it using ShowDialog. The user enters the details and clicks OK. You then get the data from that form and pass it along to the method that creates a new document.

So what's the problem??

If you're using an MDI layout, then the currently active child form will be in the MdiParent form's ActiveMdiChild property.
Now that I get to the bottom of your post, I see that you don't have much experience with designing an application, let alone designing a moderately complex one like this. You've got a LOT of learning to do, and you're not going to get it from a bunch of forum posts. You're asking a bunch of questions on how to implement very basic functionality, like putting up a small form to ask for resolution values and tracking windows you have open. These are things that you should already know how to do before moving on to implementing actual drawing on a form.

like the subject saying,i understand the principle of the reverse index,but how can you create it?can i use the VB.NET to do it?please give me some advice.thank u.

What do you mean?? This is something you do to a database table and support for it depends on the database. Access doesn't support it. A better place to ask would be the SQL Forum.

How can I change the width of the datagrid column at run time?
Binding Datatable with datagrid.

Here's[^] a good faq on the old DataGrid. It has snippets for about a hundred different DataGrid modications.

Learn about datagrid column styles. It is easy to change the width using
ColumnStyle.Width = ###

Hi All
Require a program using VB.NET 2003 that i can use to consume a web service to soap or wsdl and 1 client server but must be cross platform VB and JAVA for instance.
Thank You

You've come to a good site for that. Have you looked around for articles?

They are two different languages and platforms, good luck. You will have to have some kind of communication bridge between the two. Probably through sockets and listeners.

Hi,
I found some code to create DSN programmatically and thought of developing a tool to download data from SQL server to Excel. The main need of this tool is to develop an application which accepts SQL query at runtime instead of embedding the query in the code itself.
The application works fine for simple queries like 'select * from XYZ'.I am getting the output in Excel sheet for the above query. but if i give complex queries, i'm geting only the column names in the excel not the data. The complex query works fine and gives output in SQL query analyzer.
could you please help me?
thanks

Nobody would be willing to open an unknown .exe anyways. So don't even bother.

How can i load data from a server database unto a datagrid on a client applicaton
bizzo
|
|
|
|

To access data from a server by a client system, the method depends o how are u connecting to DB
If u are using ADO and ODBC you just have to change the server location in data source...
On the server end you have to make it sure that the DB server is listening to the IP of client...i.e. Is your DB server is configured to listen to other IP's or it is just configured for localhost
Hope this will help you a bit...

Look at http://www.connectionstrings.com[^] for the connection string you want to use ( not sure if you are using odbc, ole, ado, etc ).
You then need to have your datagrid setup on the client app and tie the datagrid to the query. I'd do a search here at CP and on google before venturing further.

I had made a application in VB 2005, with a form size.. By enabling the auto scroll property i am able to manage the situation when the target screen (monitor) is smaller then native form size.
When the target monitor is bigger and the user wants to make the application full screen, i want all the controls to be aligned and also grow in size depending the screen size...
Is there any way i can achieve that
Regards
Nishkarsh

This involves proper use of each controls Anchor and Dock properties. Also, you may have to put groups of controls in various layout panels such as the Panel control, TableLayoutPanel, FlowLayoutPanel, GroupBox, SplitContainer, ... What and how you do this depends entirely on what your control layout is and how you want it to behave.
Start by creating a new project and dropping a couple of contorls on a form, playing the the Anchor and Dock properties of those controls, then resizing the parent window to see how they behave. Then add a TableLayoutPanel and start playing around with that, dropping controls into the panel.
Noone is going to be able to tell you step-by-step how to do this. You simply have to experiment with the stuff to learn how it works, then make your own decisions on how to layout your form based on what you've learned.

Thanks for your suggestion Dave... I will the same...
I was wondering if there is any com component or something like that available they way it was there for VB 6
|
|
|
|
|
No there isn't. Besides, how would it read your mind as to how you wanted the controls to work?
