View 2 RepliesIn Visual Studio 2008 I am using :Private Declare Function BlockInput Lib "user32" (ByVal fBlock As Long) As Long To stop input from occuring during a search-replace operation.
BlockInput(True) ' do not allow input during search and destroy
Dim cursorIcon As Cursor
cursorIcon = Cursor
Cursor.Current = Cursors.WaitCursor
Then setting it to false at the end of the operation. It did not work, so I thought maybe it was because I was calling it from a child window, so I created a function in the mainwindow, and ran it like this:
FrmMain.BlockFrmMainInput()With these functions is the Main window:

It did not solve the problem. I thought maybe it was because I was running under the debugger, so I tried compiling and running it debugger-free, but that did not do any better. I am still getting input when I double-click the mouse on either form.
Dim num as integer = 1.60285253
Msgbox(shorted num??)
I want msgbox to show only shorted version of that number, so It should give 1.06
And is is possible to make it round third number to higer? If I want limit it to 2 numbers only, it should show 1.06 as 1.1, but if number was 1.04 it shows shortened number as 1.0.
I have a label and sometime the text for this label is longer than it can display. I am more concern about the end part of the text than the beginning. How do i make the label show the end part or make the text scroll automatically. And how do i know the text extend passed the length of the label?
View 18 RepliesI'm trying to time how long an operation takes in Visual Basic (VS 2008) but its not working. the code I have is as follows:
[code]...
this is in an OnClick event, so what happens is that the user can click a menu item, and it goes and sends any changes it has to a database, and pulls down any new changes to a local data cache. This operation takes time, depending on how many changes are on the server and how many are cached locally. I've thought about making this a background task, so it doesn't draw away from the main app while it's running, but before doing that, I'd like to get an idea how long the operation takes. Since I can't exactly do a progress bar, I figured using the stopwatch would tell me how many ticks/milliseconds would occur between click, and when the "total synced" message comes up, but every time i run it and do an update the message always shows 0 ticks/ms. I don't think it's accounting for the delay, just from start to finish. Is there any way to make it so it detects a message popping up and times off that?

I have a scrollable drawing (in the form paint event) with a height / width ratio up to 1: 10 . I can see the entire drawing by scrolling with the left and right arrow keys. Problem is when I need to save or print the drawing.
1. - If I try to print or save with the: PrintForm1 or with some code for a screen capture I get only part of the drawing, which is seen on screen.Is there any possibility that I save the whole drawing (the entire form, even the part that can not be seen) as a bmp or png ... (something like extended window in "Snagit" program)?
2. - If I want to print the whole drawing, I know that I have to make in a several pages. Does anyone have a similar example of this?
Here's the (Timer1's interval is set to "1" in the designer, and it is set to "Enabled" in the designer as well.)
vb.net

timeElapsed = 0
Timer1.Start()

The issue is, timeElapsed always comes back as equaling 0, so fileCopySpeed always equals infinity. Also note that test.dat is a 100MB file. There's no way it's getting copied in under 1 millisecond!

View 4 RepliesI draw text (comment on item in an invoice ) inside a rectangle.
[Code]...
I have no problem, the text appear on several lines and it is well wrapped. But if the text is too long to be drawn inside the rectangle, I need to draw the text not drawn in another rectangle (on another page). How can I know the text not drawn in the first rectangle ? I think it is more difficult to use MeasureString because the text is wrapped.

View 8 RepliesQuick query...I'm trying to scan a long string and return any values that occur between the tags <FileName> and </FileName> I've got a bit of code here to use regular expressions to return the position of the occurunces of both substrings..Just wanted to find out if there is any way to scan for both substrings within one loop (as im currently doing 2, one for the first substring and one for the 2nd) so I can use something along these lines:
ringlist = Mid(XMLRESP, (startloc + 1), (endloc - 1))
MsgBox(ringlist)
to msg box the value between the substrings...either that or another approach to return the value between the 2 substrings (it can be of variable length)
Dim patternstart As String = "<FileName>"
Dim patternend As String = "</FileName>"
Dim matchesstart As MatchCollection = Regex.Matches(XMLRESP, patternstart)

22 (fix value) + item code (6 characters right justified) + 00000 (fix value) 2205909100000 how should i change my code to obtain this result?
2. The programs every time it runs creates a text file which i also attached it plu1.txt, when i try to open it with notepad i see all the lines justified, on the other hand when i open the text file with Wordpad or ConTEXT the lines are not fixed, others are longer others are shorter? What should i change in my code in order to have every line fixed lenght... The code i am using is the following
Dim myReader As SqlDataReader = myCMD.ExecuteReader()
Dim fNextResult As Boolean = True
Using myWriter As IO.StreamWriter = New IO.StreamWriter("c:everest

3. third and last question is that my program every time it ends show up a pop up menu which says "Text is created." Instead of this i would like to create a file lets say log.txt and every time the program runs, it will overwrite on the log.txt file a line like this: system date + Text is created + with X lines (where X are the lines of the text plu1.txt) ex. 26-10-2009 14:56 Text file created with 15 lines
This is probably a really simple thing. Basically, the user clicks a button and a potentially long running task happens. I'd like to do a few things like toggle the button's enabled state, show a spinner, etc. In VB.NET Winforms I'd just do Application.DoEvents() and the updates would happen and the code can continue. How can I do this in ASP.NET? (preferable serverside or minimal javascript)
View 2 RepliesI am developing a web application in asp.net vb. My current situation is,I have a main site say [URL] and another site for generating reports depending on certain user ids say [URL].If I click a button on [URL] I have to switch on the generate report page on [URL] and return to[URL]. [URL] should generate report and set a flag in database of [URL].Currently I am redirecting to the page in xyz.com and add the long running task to queue as follows and redirect back to [URL].
If ThreadPool.QueueUserWorkItem(New WaitCallback(AddressOf LongTimeTask), New Object) Then
Response.Redirect(returnURL)
End If
But the problem is its not dependable. Means some times the queue is executing correctly but some times not. There are no errors in long time task. Just the queue is not executing.
Edit So the solution I posted from Jenner at VBforums was, obviously, in VB, and I used an online converter to port it to C#. Something was lost in translations, and that's why it was 10 miles off. I'm guessing I am just misunderstanding what the algorithms at the Proj.Net discussion boards are for and that's why they weren't doing what I wanted them to.
