I have a progress bar on a Windows Form which displays the number of records as they are retrieved from the database.The problem I'm having is that the entire Form.Load() method seems to run prior to the form being displayed, which means all my code updating the progress bar is gone to waste.
View 4 RepliesI try to create a MDI child form that should be resizable but it should not have a title bar visible. Is it possible? Or is there a better method to display child windows within a main form than displaying other forms. In this case the panel would be visually better than the form but the panel cannot be set to act as a child like a form.
View 3 RepliesI am making a change to some code written in vb.net, its a winforms app. The menuitem uses the System.Windows.Forms.MenuItem control. I need to display the values in that drop down menu into 2 columns. It displays a number of items and therefore is too long.I wish to display the items side but side in 2 columns. In C# you can use ToolStripMenuItem which allows you to display multiple columns. Even though ToolStripMenuItem is available in Vb.net its difficult for me in the current app to switch to that tool.
View 3 RepliesI have created an application that uses two forms one is displayed on a touchscreen and is a basic input form, the other is displayed on a large display monitor and is basically an information form, both displays are connected to the same pc. The program works great I have just one annoyance is if the program is restarted it displays both forms on the touchscreen and I have to drag the information form onto the big display. Is there a way to specify on load that each form gets displayed maximized on a certain screen so I don't have to drag one form onto the correct screen?

.NET developing and have a simple question, i've been stuck on this for a while and searched many forums first with no solution so i'm posting myself. In VB for excel i've used Screenupdating=false to disable the screen updating however now i'm creating a visual studio 2010 windows forms application and its not showing up as a property. Here's the code i've tried.

I am trying to use values from form1 in my project, in form2, but Im not sure how to do it. I've tried

I have the requirement to create an application that has multiple front ends developed using Windows Forms, WPF, ASP and Compact Framework Mobile Forms.I would like to be able to create a series of obejct representing the business logic and have this logic accessible from the various front ends available. My first thought was to use remoting as I'd like to be able to pass the business objects back and forth between client and server but the compact framework doesn't support remoting and also transferring a full framework business object to a compact framework business object doesn't seem possible.My next thought was to use web services but again the passing of business objects seems to be very hard to accomplish. Without doing this I would have to create individual web methods for each business operation.
Finally my next option is to use sockets and write the whole client/server logic within some classes and expose them to the UI/Business layer. My only problem with this is it is not scaleable should the number of clients increase dramatically whereas using remoting or web services I can host the solution via ASP.Net.Does anybody have an ideas on the best way forward for this or even have any input on how they would write an application that required a windows form, wpf, asp website and mobile device GUI all of which want to use the same business logic?
I would like to know if its possible to start up a second windows forms inside the parent form. Ex: A button is pressed and a new form is showed. I would like to keep that new form inside the parent form, and have it not be able to go outside the parent form.

View 3 RepliesI was playing a game recently and saw that they could use args in the shortcut, and I decided to try to impliment this into my application...so far, I got: (runs this sub on load)
Sub startup_args()
If Environment.GetCommandLineArgs.Contains("+game") Then
Dim path As Array = Environment.GetCommandLineArgs
[code]....
just to see what it returns, but the application crashes. I also tried path.tostring(), but that didn't work. When I did:
If Evnironment.GetCommandLineArgs.Contains("+game") Then
Dim path as string = Environment.GetCommandLineArgs.tostring
MsgBox(path)
[code]....
but that returned the value "SString.Array[]"...
What is the vb.net equivalent to accomplishing this?
static void Main()
{
frmCalcView view = new frmCalcView();
[code].....
My question is, am I able to share a business logic layer seemlessly between the two presentation layers or is there anything I need to watch out for. I'd really like to not have any duplication of business logic, so any advice would be more than welcome.

In my VS-2008 (VB.Net) application, I am using a background worker to make my main form more responsive. In case of any error (in DoWork event) I m displaying the error on another form. In this case main form can�t be a parent of error form so if main form is clicked, error form go in the background (behind main form). I want to restrict the user to interact with the main form while error form is appearing. Is there any way to associate these two forms such that error form always appear in front of main form.
View 1 Repliescurrently i am using a threadpool that contain a number of thread. This number of thread can be different everytime, sometimes 5, sometimes 10, sometimes 15 and so on (multiple of 5). So now i have it working good by using for loop to queue the thread into threadpool. Now the problems is i do not know how to make the progress bar depending on my threadpool. I want my progress bar to complete only when all the thread are done. After searching google, i found that maybe it can be solve by using AutoResetEvent(false), but after i apply to my program, it still did not work, my program hang at xEvent.WaitOne() method and didnt proceed further, anyone can explain to me how to solve the problem? Or got any other ways? For your information, only 5 threads can be running at the same time as the requirement state so (so i set the setmaxthread to 5 already).

View 1 RepliesI am wondering how do I update a Progress Bar that resides in Form1 (for example) from a newly created class called from the Button in Form1. I have read several tutorial about backgroundworker. Most of the googled tutorials have their "long process code" in the do_work event. I have tried them and got it working from within the form itself.
However, there are 2 parts (long process) in which I wish to incorporate the updating of the progress bar; First one being a long sub routine that is in the main form (Form1). The second one is another long processing function that resides in a class. It is the second one that is giving the problem as I have no idea how to call the backgroundworker.reportProgress() to update the UI.
Here is the sample flowchart that I have created for the second long processing function:
I wish to insert a new instruction that says "Update the Progress bar that is in Form1" after the current instruction "Store the member into a collection".
I want to make an app that gets the progress bar to 'pulse'
My code doesnt seem to work though!?!?!
Public Class Form1
Dim Value
Dim NoValue = "Add"

I am new to VS 2008.. It is possible to change the progress bar loading color (green) to other color? How to change it?
View 3 Repliesso what I want to do should be pretty simple. I've been following the examples found here Using the BackgroundWorker Component - VBForums . I've been successful, but I'm not smart enough to put it in my project.
What I'd like to happen is this
1. I hit a button to load data from a dataset....
2. have a progress bar show until this action is complete.
The main problem is that I can't figure out how to tie the "progress bar" to the action of "pulling the dataset"
I'm sure this is a crazy question for you all, but hey...
Would I put all of the coding in the button_Click sub?
