VS 2008 Any Coding For Which It Disables Entire Form Until Process Is Completed?
Jul 23, 2009
My form contains lots and lots regular expression and other things in one button. whch when pressed takes some time to process.. so the form kind of gets stucked while the processing is bieng done.is there any coding for which it diables the entire form until the process is completed? like disabling the entire form and showing a text "please wait ... processing data" so user can not use other buttons or features at the same time or it might get crashed.

I have to install whole bunch of self extracting files every now and then.. so, I was trying to automate the process...
Using process.start ("filename"), i was able to run the exe file. After that i send Alt U to Unzip the content.. Finally the Self Extractor sends message "xx files unzipped successfully..." or similar...
Now, how do I find out the the extraction is completed or the msgbox "xx files unzipped successfully..." popped up ? (I don't like to go thru the window title as there might be other thing going on...)

I have a user who wants to print the form that is on the screen(the entire form not just the data) on the click of a button, is there a quick and easy way to capture it and print it. Kind of like a screen shot? I suggested that they could just do alt/printscreen and capture the form that way and print it but they want it all to be done from a print button for them.

Question is related to rather simple programs typically presenting some data in a few datagridviews, charts etc. And consisting typically of a main form and one or two settings forms.I'm trying to program in a layered structure, pulling every bit of code out of any form class, and having a seperate "program class" for any form that I make. Now.. So far you can't complain on that I guess, but how to do this in best coding practice? In the form class I make a member object of the program class, hence making the program class a child of the form. Now I'm able to create events in the child class, and have handler methods in the form, without writing delegate classes (it seems). Now, that is fine, as it enables me to update the form controls with such events happening in the program class. However, how do I send events the other direction, from the form (parent) to the program class (child)? I guess I don't have to use events, I could just use the member object to access public methods in the program class directly, with passing of parameters from the form controls.. however, is that good practice? Or should I use events also that direction, and how to make that work, do I need to introduce delegate classes

I have searched google with this error in relation to Process.MainModule.FileName however none link with the error message, "Only part of a ReadProcessMemory or WriteProcessMemory request was completed".There however was one thread on these forums suggest a 64 bit issue however that was soon excluded as it was reported also in a 32 bit enviroment. The marked answer to that thread suggested it is a security problem however I don't think anything has been changed in relation to that comapred to a 'clean' project.
"If it is a security problem, you may try to run your application under the debugger" Process.MainModule failure I am in-fact debugging this application through Visual Studio so I am not quite sure what to do next in the process of diagnosing this problem. I am debugging using 32 bit in a 64 bit enviroment because of DirectX compatability issues?

I am looking for a VB.net book that strings me through the entire development process of an application (Prefered: WPF ,LINQ ,ADO). I have read a few books on OOP and VB.net with small code samples demonstrating the specific idea of the chapter.I think it would be really helpful if there was a book that programmed an entire application that uses a sql database (Northwind , Adventureworks).

I have another question (and anticipate that I will have about two more before I'm done with my class project). Here is my issue (and I'll copy and paste my code for clarification). I need to link up the control from the form on either side of the current form that I'm working on so that if I click on the buttons that I'm titling previous and next that I can click on the proper button and either go directly to the previous form or the next form. I was successful in doing this for two earlier forms on this project (with some direction from a couple of helpful people on this forum before), but for some reason, no matter what I details I use the controls do not connect to the previous and next forms.
Option Explicit On
Option Strict On
Option Infer Off

I am working on a program and for some reason when I run it as an executable outside of debug mode, if I run the main subroutine of the program, the process remains in memory after being closed. Even though the form is closed/gone, it will be in the process list and I have to ctl-alt-del to remove it. If I exit right after opening the form without doing anything, it closes like normal. I am closing and disposing everything I can think of, and I've never had this problem before. This is how I am exiting, but the problem also occurs if the user "X's" out.
Me.Close()
Application.Exit()
I have a couple web file requests in my program, which is the only thing out of the ordinary (code-wise) for me, don't know if those are the root of the problem. I can't imagine this is the first time this has happened to anyone, but I couldn't find anything helpful with my search terms. Any ideas/common solutions? I can post sections of my code if it will help, but the whole thing is pretty long and I couldn't narrow down any potential problem areas.

I have searched everywhere, and have not found an answer. I would like to know how to enable your form to detect if a process is started. Something like this:
If Process.Start("Process.exe") Then
MsgBox("Process is running")
Else
MsgBox("Process is not running")
End If

I need to disable every control on my Form so that the user can not click or press any key that will change values of listboxes and other controls on the form. I need to be able to lock the whole Form like this because as part of the project I have to print the form 3times with 3 different colors and the only way I've been able to get it to work is with a timer. So for about 3 seconds the form is changing colors and printing itself, so in between that time the user could accidantely click something and change a value on the form when all three prints should be of the same form, only difference is in the color.I can't use disable as that will make all the controls look faded and messed up, I need a clean way to prevent anything from being changed.

I got a strange form in my project that doesn't close when I close it, so every time the user will use it, it will stay on system processes. The form is not even shown on the taskbar when it is loaded. It is just a regular form - System.Windows.Forms.Form.

Ok so i'm trying to set up my program so that when I choose WinRar it opens a new window asking which architecture to use. I have a combobox set up with both architectures in it. I have the accept button disabled so that you have to choose an architecture and I figured out how to make it so that when you select one architecture it will enable the accept button but if you choose the other architecture it disables the button.
Private Sub cmbx_rar_wdw_arch_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmbx_rar_wdw_arch.SelectedIndexChanged
If cmbx_rar_wdw_arch.SelectedItem = ("32-Bit (x86)") Then

I am really new to Visual Studio and VB and I am having trouble closing a single form:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Close()
End Sub
When I use Me.close() associated with this button it closes the entire project and not just the single form can anyone.

I'm trying to make my form nearly transparent when the mouse is not inside the form by changing the opacity.I'm having trouble because if the mouse is moved quickly, I can't get its position accurately. when the mouse is moved into a control, it's considered to have left the form. Is there an easy way to do this that I might be missing?

I've been asked by management to convert all of my applications from VB 2005 to VB 2008 (in preparation for taking them to VB 2010). I have a VS 2005 application that uses an ADO Data adapter which was defined using the GUI. I normally define my connections in code, but have been asked to get away from that in favor of ADO (and similar) data adapters.When I run the conversion wizard in VS 2008, it appears to convert this program, with some warnings and I get the 'Conversion Completed' dialog box. However, the VS 2008, will not let me close the dialog box, even after waiting for 3 hours. The only way to get out is to reboot the system.

I have a program and wish to generalise its appearance at startup on different machines. This worked OK until I moved it onto a Windows 7 unit with a 22" screen. The front page covers less than 2/3 of the screen. I know I've asked the system for 'working area' but could not find a reference to the entire screen which other applications seem able to use. How can I catch up with them? The code is from VB in VS2005. Is this my limitation?

I am creating a bulk media converter. In order to do this I need to go through each line in a list box one after the other and run the conversion function. I am trying to use the following:
For Each item In listVideos.Items
conversion code

However this makes the program want to convert all videos at the same time... is there anyway to get the program to convert one video and then after the conversion code is completed to move to the next one?Should also be noted that I am using FFMPEG for this project.
