View 1 RepliesI have a background process that require about 1 min to come to completion.
All the data are in memory and it does not need to read the harddisk.
I have noticed that the CPU utilisation during the full minute is less than 20%
is there a way to force the application to use more cpu to reduce the calculation time?
I put the control in the form every thing works fine, but the problem is the priority of the sequence that the code performs for example:In the Cancel Click event there are some code inside the control it self, and in the form which hold the control I also put some code it goes fine but it first perform the code in the form and then it perform the code in the control.My question is there a way to tell the click event to perform the code inside the control first and then the code inside the holding form, (priority sequence)

View 1 RepliesAs Strings.Space Method , but instead space - new lines.For example:If I want 4 spaces, I can do:
space ("4")
But if I want 4 new lines,I have to do?:
VbNewLine & vbNewLine & vbNewLine & vbNewLine
Or there is another way and more effective? (such as "Strings.Space Method"for example)
I need to set up a list consisting of arrays of two elements. Simple, right?
Like: (code snippet):
Dim strDataPoint(1) As String '2-element array
Dim lBiasCurve As New List(Of strDataPoint) 'list of 2-element arrays
Dim lPwrCurve As New List(Of strDataPoint) 'another list of 2-element arrays
But this gives me an error msg on 2nd and 3rd line: type strDataPoint is not defined....
im creating an array that contains something like this [code]Then i need to make it so when i click on a listview item it searches for the same "Application" name and shows the path.I have everything planned out, but im not sure what i should use to do this.Should i use list(Of string), arraylist or just string(,)?I have no idea of the amount of elements it will contain. I was thinking of using a list so i can use .find without having to make a search function.Anyways, what would be the best/fastest way to do this? Its possible i might have up to 1000 rows in this array, so i want something fastish.
View 13 RepliesWe have a issue with laptops for the current client in which IE continually shows prompts to users about working offline. The laptops are on a flaky wireless connection (Personally I would much rather fix this but they would much rather just fix this issue, apparently this works better money wise. I have my doubts).
Anyway the issue I'm facing is removing this box from opening at all.. Now there are two ways I can think of doing this. A possible Hook if it is available to catch it before it comes out and stop it. Or the less nice way is to when the box comes up to automatically hit the "try again" option using a sendkeys push.

View 7 RepliesI have a splash form that opens in the following Sub of the main form of the app[code]...
The Splash Form opens and closes fine, but no controls (a text box and a graphic, on a panel) appear on the form. I knew I was probably missing something (this was far easier than anything I found searching), but at least the form opens and closes. The app actually starts with a SubMain, which is only used to control how it opens with it's registered file type.
I have a small non mdi form with only 3 controls. The user can select a name of an animal on a listbox and a thumbnail picture of it is shown on the picturebox. There is also a tton.The tooltip on the thumbnail is quite important as left/right click do different actions but for some reason the tooltip will not display unless the user clicks the form.
View 2 RepliesI am making an app (sorta like a computer lock) that won't let you do anything on your computer until you type in the password. I am using
Public Sub w_setfocus()
Dim f As Boolean
While (1)
f = Me.ContainsFocus()
If f = True Then
Me.Focus()
f = Me.ContainsFocus()
End If
End While
End Sub
End Class
And w_setfocus is run on form1_load. The problem is, the form then never shows up.
I was working on a project in vs 2005 and decided to see my project's form in microsoft blend, the form did not show and i closed blend and saved no changes. The next time i open my project in visual studio, my form1 design mode shows me some code for the windows form designer. How can i get my form back as i need to add more controls and change the orientation of some others?

View 4 RepliesI've written a small program that monitors the customer field in Quickbooks and query's a database to determine if there are any important notes for the selected customer. This works fine however, I either need the messagebox or a form to come to the front of all open windows on the system to inform the user that the selected customer needs to be reviewed.
How can I ensure that a form (or messages box) that opens in my program comes to the front of any and all application windows that are open?
Something happened to my project and it got all messed up. I am not sure what happened, but the form I was working on only shows the code and not the project itself(where you design it). I am working in VB2008 Express Edition and do not wish to start over. What happened to my form?
View 6 RepliesI've got a project that generates a sql query and returns the results. I want to place a time/counter on the form that shows how long it takes to return the query from the server. Basically to count up in seconds from 0 while that sub is executing. Would threading be the best way to do this or is there another way that I'm missing?
View 2 RepliesI got a couple of issues with my windows application VB.Net. I seem to cannot set the form to be invisible before it shows up for a second, there is no option in the properties of a form and also if I set the form to visible = false before the form is loaded it doesn't work.
So this does not work:
Browser.Visible = False
Browser.Show()
and this does work but the form shows up for a second which I am still not very happy with
Browser.Show()
Browser.Visible = False

I am using the following code to create an array consisting of double values specified by start stop and step. The problem with that is that for some weird reason there is a calculation error that seems to originate from the for statement causing the values to drift after the 11th to 12th digit after the comma which is quite irritating for the purpose i am using it.
