View 1 RepliesI've created a dialog which I'd like to popup from any function or sub in any class or form that I have in a project. It would nice to have it work exactly like a messagebox except it's got a progressbar and a cancel button on it. It's job is to display the progress of other functions so it should just stay open until I close it or the user selects cancel.Now I've found many of the basic examples on the net and have got the dialog working exactly as they have shown it. The trouble is that the examples are using a counter or thread.sleep which simply adds +1 in the DoWork sub. In other words, it validates that a worker thread can update a progressbar but it's a closed loop that only exists in the dialog's class.The examples don't show how to call an unkown function in another class dynamically, they're simply a hard coded 1+1 in DoWork. To me it's not a real world example because it doesn't show how to plug into the dialog or get a communication stream from other classes and functions that are running and wanting to increment the progressbar.[code]
View 3 RepliesI have a windows forms application written in VB.NET which scrapes information from serveral web pages (who doesn't right)? Anyway, I am having problem with one particular site where partway through the page navigation my application hangs. When I press pause (or break) in the debugger, it stops on a call to System.Windows.Forms.Application.DoEvents.
Resuming execution shows that it really is stuck on this line (it does not reach the next line of code). It also hangs about the same point each time I run it (at least its consistent). Since System.Windows.Forms.Application.DoEvents yields to other threads on the same processor and then resumes execution of the current thread, I think the problem is that some other thread is not behaving well (not returning from some event handling code). I thought Windows 7 was pre-emptive, which makes me
doubt that theory but I really don't know.
[Code]...
The program scrapes somewhere between 12 and 14 pages before it gets stuck on the call to DoEvents. Does anyone have a clue why this would happen? Why would any call to DoEvents hang?

I've decided to make my own simple scripting language parser. I've created about 50% of it and it works great! I need to implement "functions". What ever program uses my parser needs to be able to connect functions to my parser for customization. I've implemented "Lua", a scripting language, in a vb.net application of mine. To connect functions to the Lua Parser it used reflections.I need to be able to (by only knowing the name of the function and its structure) call a function connected through the implementing application.

I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for

I have a vb.net app that retreives data from a MS SQL 2005 database. I have it creating an Excel 2003 workbook. In a cell of a Worksheet, I want to "Call" or make active my vb.net App via a key combination (Alt->V) and have the workbook/worksheet pass the Row number / Column to the vb.net app that will get the data and post back to this Cell. This combination (vb.net and Excel) is my report builder app. So I want to go back and forth between vb.net and Excel, passing the needed data from each. How can this be done?

I have a slight problem , using vb 2008 i have written some code that checks the current datetime on the computer. This gives me the answer in the format mon, tues etc. what i now want to do is to use that to call a spreadsheet dependent on the day of the week. here is my code so far
Code:
Dim TIME As DateTime = DateTime.Now
Dim FORMAT As String = " ddd "
TextBox1.Text = TIME.ToString(FORMAT)
[Code]....
Now i have tried the private sub eg SATS() on a separate button and it works perfectly . so it appears to be that the sub is not been called. I think it is probably a syntax where the datetime answer is not been recognised, in that textbox1.text = "sat" is not the same as datetime = sat .
How can I call a function from inside another function and suspend the calling function until the called function is finished? I hope I can get some replies because I don't know how to ask the question and make sense:).
Anyway what I am trying to do in steps:
1. The user clicks button1 which triggers the click event.
2. From the click event I call a function
3. I then pop-up a form, that has instructions for the user to read.
4. After the user has read the form he will click the "Done" button and return to the calling function.
The problem is the the calling function continues to execute. I want to stop execution of the calling function until the users clicks the "Done" button on the instruction pop=up. I know I can use a msgbox but the instructions can be lengthly and does not look good in a msgbox.
I have tried the Call method with return in the "Done" button click but I can make that work. I also tried a goto statement but I can get that to work either. In the call statement I said call frmInstruction.show() and it got there but as I said the calling function continued to execute.
ive two custom controls, which are used to draw and edit etc...(like paint but customized....) i want to save their images with a single click....So im using the Getimageofcontrol function to do it....its code is below:::
Public Function GetImageOfControl(ByVal c As Control) As Image
Dim rc As New Rectangle(c.PointToScreen(c.Location), c.Size)
Dim i As Image = New Bitmap(rc.Width, rc.Height)[code].....
and the code to call this function for saving the images is simply.. ...
GetImageOfControl(pboxd).Save("c:78.jpg")
GetImageOfControl2(pboxf).Save("c:lp.jpg")
but the problem is that both the images have the same content....
I have a function where I am performing a lot number of database operations inside a Sub. The operation when called directly like:ExecProcess()
takes about 11 seconds to run.However, if I create a Delegate, and call the sub using BeginInvoke(), the very same process takes over 40 seconds to execute.Here's the threaded code:
Protected del As ProcessDelegate
Protected Delegate Sub ProcessDelegate()
del = New ProcessDelegate(AddressOf SELocal.ExecJob)
Dim cb As New AsyncCallback(AddressOf Me.ExecJobComplete)
del.BeginInvoke(cb, del)
Anyone know what may cause a function to take longer inside a new thread, rather than calling directly?
Some programs implement command parameters, Like my favourite computer game - Crysis - has them and windows media player has them.But how could i implement them in VB.NET..I want to have a component of my program built as a seperate exe - so it can be an Optional component.But of course the seperate exe, on load, needs data passing to it.So i need something like Process.start("Componentname.exe", "/StartDL <Suchandsuchastring>)/StartDL will need to call a function, and the string that it uses will be given to the function to initiate a download?

I want to write an app which would automatically fill an internet form with different inputs, depending on its own input.The thing is, I have no idea how the VB-Web interface works. I have seen the inet controller, but the only use of it I've seen is retrieval of the data on the web page. What I actually need is:
a. VB to open a certain web page.
b. VB to choose an option from a drop-down list.
c. The page will change to another page (depending on the choice in b).
d. VB to fill a form consisting of drop-down lists, text boxes etc. After each of the fields is filled, the page refreshes itself.
e. After all fields are filled, VB should click on a link which would open a different part of the form.Follow steps d+e a couple more times, and then submit the form by clicking a certain button.
recently I've been going through some website login automation and ended up with creating a simple my own browser quite happily, to open websites and login straight away.
But I found out that I can't automate some of the websites I was going for, because the html code of the login forms is not shared and cannot be seen in the source.So I'll give you guys a couple of websites I can't deal with and please advice if it is possible to do stuff with them:[URL]...
