Perform Other Tasks When A Form Is Loading?
Jan 22, 2012
I have a main(frmmenu.vb) form which is the mdi parent of other two forms (namely frmcandidatelist.vb and frmviewcandidate.vb)...........Two forms are displayed simultaneously on frmmenu each separated by split-container(frm-candidate-list.vb on left side and frm-view-candidate.vb on right side)
Frm-candidate-list.vb shows name-list of customers on a datagridview. While i click on a item from that list, details of the respective customers(like name,id,photo,address,etc) is displayed on the right side form(frm-view-candidate.vb).....
But there is a problem. Loading details of a customer takes time(since i have to connect from remote database)... So the whole program becomes hanged(like) till details are loaded.....

I am creating a server-client type application that allows the network administrator to perform tasks on remote computers by using TCP sockets (TCPClient and TCPListener).The server application needs to send out a message to a client machine (with client application installed) and from this, the client application will send back the required data (i.e. system info, task progress etc). This part works fine.However, I am having trouble in getting the client application to constantly listen for an information request in the background. It should be listening whenever the application is running. What I want to do is to have an event handler which, when a message comes through, acts upon the instructions to send the relevant information back. The server does not need to constantly listen for data, as it will only receive data after it has sent a request.

I want to link sql server and vb.net (ADO.NET) . I'm using visual basic 2008 express edition and sql server management studio.
My problem is how to perform a search starting from the completion of a form (in vb.net ). On pressing the button search it verifies if the records are in the table (in my case FoaieParcursMasina).
SQL Server:
Step1: Create the table and insert into them the values (full DDL):

I am currently developing a small capture system program. What I intend to do is to create a hot key for my program to capture image (press F8 then it will invoke a button to click automatically). What I manage to do for the time being is only registerHotkey procedure. (Please refer to the coding below). I am unable to create a hot key which perform like a button click.
This is just a testing program: I have 2 forms specifically. Form1 with a button and form2 with a picture box.
I would like to run this program where I can just simply click F8(for instance) instead of clicking the button.
For the time being I am able to run this program and put it in the system tray when I minimize/closed it. When I click F9 the program will pop up again. What I would like to do now, is clicking F8 (for instance and the program able to click a button from form 1 automatically). I had used PerformClick but still unable to do so.

Is there a way to turn off all visual updates to a .NET form while I am manipulating it? When my program first loads, for example, I set the tab control to the tab that was last open. The user can see the program switching tabs.
I have looked into SuspendLayout and ResumeLayout, but either I don't understand what they are doing, or I am not using them correctly, because they don't seem to have any effect. Someone told me that there used to be a way to turn off paint events in VB 6. Does this still exist in .NET?

How do i load the Main form of a WPF so that a seperate thread goes and gets data from the database while the form is in an apartmentstate ? (drag-able / movable) I Know this is possible with opening a new window from your main form like this :
Private Sub openOrderWindow()
Dim OrderWindow As Orders = New Orders
OrderWindow.ShowDialog()
End Sub
[code]....
I've tried putting MyBase.ShowDialog() and .Show() and .9000+ other things The only benefit I've got out of using a seperate thread to load from the databse is i can see the screen right away (as oppose to it being a transparent box until it loads) but i cannot move it around or minimize itis there any way to make it Movable while it loads?

Does anyone know of anyway that it would be possible to speed up the process of loading forms.With VB6, forms (simple ones) was extremely fast but with VB.net, the initial loading of a form (even the simplest one) takes very long. Although it gets better once it's loaded once and the reloaded the next time (almost instanttaneous), but the first time loading gives a bad impression to any user that .net is actually much slower.

I've got 2 forms; form1 and form2.
Button1 is added to form1.
When I click button1, I want to close form1 and open form2.
I tried the following.
me.close
form2.show
Its not working. Form1 gets closed but form2 is not showing up.
When I use the following code
me.hide
form2.show, its working.
But hide will not unload form1 and it will still occupy memory.

When my form first loads or when it closes a number of events which I have in my code fire, such as a combo box's selected index changing as it populates. Is there anyway to prevent this from occuring? Currently I use a boolean variable which I set to true/false depending on if the form is loadig or closing and then each of the events first check this value before they fire.

Problem: Form hasn't fully initialize but shortcut keys can be usedDetails: Launch an mdi child with database access retrieving data, and user is already using the shortcut keys while the data is still been retrieve which results to error since object hasn't fully initialize yet.
Goal: Hinder user from using shortcut keys by disabling the keys at initialization then enabling it after all objects are good to go.
Another Situation is:A form with a gridview and a button.I got a hotkey that when press, handles a gridview getfocus event.
The problem is that the gridview is still making its instance and when press the hotkey, it activates the getfocus property of that gridview(which is still creating its instance).

Problem is, i do have two forms. Form-1 is the parent and Form-2 is the child. Form-2 is having so many executable functions built in. Therefore when i am calling form-2 from form-1, always that takes few seconds to upload(although negligible).
Now I got a very nice ajex_loading.gif picture (moving) form Google and was thinking why not showing that pic in between my form loading process. Added PictureBox property. Telling it to show()...but still that is feeling shy at me
