I have a Form that I named "Taulukonvalinta". This has 2 buttons (Ok and Cancel) that are defined as OK and Cancel.However, when I call the actions from my main form, Form1, only the "OK"-action works.>[code]
View 4 Repliesjust had a walkthrough in class and the example code our teacher gave us does not return a value. I am having alot of trouble with my current assignment because I do not see whats wrong with it. It is supposed to take two numbers entered by the user and add them together for a total with a tax rate, but it continues to return all 0's heres what the code looks like:
Public Class Form1
Private Sub BtnCalc_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles BtnCalc.Click
[code]....
Consider the following:
class Bind
{
public string x { get; set; }

I am trying to use impersonation when running an exe on a server. It appears to log in correctly but windows still doesn't recognize the Username.

In here output is:

Which looks correct almost all web servers will process the two of the following as same request:

What's the best way to fix this behaviour is there any API to do this, or shall manually create a new URI and remove all // in the path?

How do I get the SuspendLayout and ResumeLayout to work correctly in regards to a listview. I have added these lines of code before and after I have added the items, yet each item is still being displayed as I add each item.
My code:
Dim x As Integer
Dim startTick As Integer = Environment.TickCount
lstFiles.SuspendLayout()
For x = 0 To UBound(cacheListArray)
[code]....
I am adding 2000 items. This takes 7 seconds. I was told that it should be a lot shorter than that. Is that correct?
New code:
Dim ListViewItemArray(-1) As ListViewItem
ReDim Preserve ListViewItemArray(UBound(ListViewItemArray) + 1)
ListViewItemArray(UBound(ListViewItemArray)).Text = file.Name
[code]....
Nothing is being added. What have I done incorrectly?
After upgrading my solution with both c# and vb.net projects I have encountered some problems:
1. When for example writing Public Property MaxDate As Date and pressing enter it does not create the Get/Set values
2. Refactoring is not available
3. The properties window is blank when viewing classes (normally I would see Serializable and COM properties to the right)Intellisense works and the above problems work in new projects.
My debugger doesnt work correctly anymore and I want to let it work correctly cause i've done some changes in my project but when I click on debug then it just shows my old layout.

Add a new report to a windows forms project. Now add the table data region from the tools. If you don't already have a strongly typed dataset displayed in the data sources view, get that ready. Now do the tried and true easy-to-use trick of dragging a field from data sources onto the table's details row.

I validate a DataGridView with the CellValidating-eventhandler.That works fine. However, I want to avoid validating when the user presses the Cancel button. In the sequence validation occurs before the event CancelButton.Clicked.
View 1 RepliesI have a VB.NET form (CopyScenarioForm) with a OK button (DialogResult property = OK) and also assigned it as 'Accept Button" for the Form.
I show this form from my main Form (mainForm) using
If DialogResult.OK = CopyScenarioForm.ShowDialog() Then
DoSomething()
End if
Now when user clicks on the CopyScenarioForm.OK button, I want to validate his entries and if invalid I want to 'Exit Sub' from the OK button's click handler but when I do that the form still closes out and DoSomething() gets executed. Is there a way to stop this and keep the form alive and only exit if the inputs are valid. I noticed, if I change the OK button's DialogResult property to 'NONE' instead of 'OK' then it doesn't cause it to close. but then how Do I know how the user exited the form to execute DoSomething().
I am working on an application and have encountered difficulty using the response to a message box question. I am trying to call one form if the user clicks yes another form if the user clicks no, please have a look at my code and see if you can see where i am going wrong because no matter whether i press yes or no the frmTransactionMenu is being shown and never the frmExit
Dim response As DialogResult
MessageBox.Show("Would you like to complete another transaction", "ANOTHER TRANSACTION ?", MessageBoxButtons.YesNo, MessageBoxIcon.Question)

I have a code to print in VB.net. I don't have any problem with the printing as it works, but there is a part which is underlined by green, a warning on "DialogResult = OK". Why the DialogResult = OK is underlined by green colour? The printing work only this underline is making me puzzled

I have the following code [code] This loop takes sometimes up to a minute to execute. I would like to display a message box giving the user the option of terminating the loop.

I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.
I have a form that works on my local Machine I created into. I have Office 2007 on this machine. I created the Form with the Excel 12 Reference. I move the Entire conetence of the Project folder to my work computer. Which has Office 2003. Do I need to recreate the form with the Excel 11 reference. I could not get the form to work on work computer. IT has a com error. I am acessing the EXE for the debug folder w/in the Bin Folder.
View 7 RepliesThis should be simple, but the answer is eluding me. If I've got a Save action in my controller, and the save fails, how do I cancel the action without disturbing what the user entered? For example, Index is strongly-typed of "MyTable":
Function Index() As ActionResult
ViewData("message") = "Hello"
Return View(New MyTable)
[Code]....
In the Catch, if I put Return View(form), I lose the message passed via ViewData. If I redirect to Index, I'll lose what the user entered. I think I've seen the simple (correct) way to handle this before, but if you don't know what to search for, it's hard to find.
I need a procedure that cancels all the print jobs of a specific printer.
I use vb.net 3.5 & win xp pro.
Plz don't send me "restart the spool service", I need code to cancel all print jobs.
The problem is that the PrintPreviewdialog still shows when the pagesetupdialog1 is canceled.
Not sure how to cancel that along with the pagesetup on cancel.[code]...
I was hoping somebody out there could help me please, I have an application which uses threading, process and runs cmd.exe - the problem I have is that I cant cancel the command.I have one textbox and two command buttonts, button 1 is run and button 2 is cancel - for this testing purpose only (my app wont be pinging but I'm doing this for testing only) I'm hoping to enter an I.P address in the textbox and then click on Run which starts a thread and the process, which so far is working.the coding I use to run the command is.[code]Now comes to difficult part, whilst the command is running I want to click on cancel which kills the thread and process which I have done but I have hit a brick wall because even though my thread and process has been killed my command carried on running, what I would like is the moment the cancel button is clicked to kill the thread, process and the command.
View 2 RepliesI am not familiar with threads, but the project I am working on has a bunch of them. There's a thread for the main form, then threads for activities like a calculation, converting files, etc, so that the user can kick off a calculation job and then kick of a conversion job that will run at the same time. Typically, calculations can run for hours and hours; conversions and other threads may only run a few minutes.If the calculation runs into a problem, how do I cancel that thread? It looks like the threads are controlled (driven?) by the main form, but I'm at a bit of a loss.....
