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)

I have a webbrowser and on a form I need it to fill text. The problem is, in order for the submit button to activate, you have to atleast type in 1 letter for it to update and make it send. The problem is when I do document.getElementById("p1").innerHTML= "SSSS" it works but it wont update the submit button to allow me to submit the form. What should I do?
View 2 RepliesI have a view with a few checkboxes that can be selected or unselected. I'd like to always register any change in a checkbox, without the use of a submit button (the user could forget to do it, and it would waste time). So, is there a way to handle this inside the view? Up to now, I've only used the controller to do that job.

In 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.
The background: I'm in the planning phase of an Application. The Application will work with a set of data which will be illustrated on a diagram. I plan to have a class for dealing with the graphical issues (e.g. creating the diagram plot, zooming, drawing lines on the plot, selecting a data point by clicking, etc.) These will be handled by MouseDown, MouseMove and MouseUp events.

I've created an application (a simple calendar app w/vb.net) for my own use and would like to share it with you guys. I don't want money for it, just for the fun of sharing, and maybe get some feedback on it, not regarding the code, but the usability and concept.
However, this might not be the right place, as this forum is more about getting help on specific questions regarding code.
I've looked at codeproject.com, but it seems it's about presenting particular topics concerning code.
Does anyone know of a good place/forum to share and get feedback on finished applications?
My software will simulate a few hundred hardware devices, each of which will send several thousand reports to a database server.Trying it without threading did not give very good results, so now it's time to thread.Since I am load testing the d/b server, some of those transactions will succeed and a few may fail. The GUI of the main program needs to reflect this. How should the threads communicate their results back to the main program? Update global variables? Send a message? Or something lese?
Now, if I update only at the end of each thread then the GUI is going to look rather boring (and I can't tell if the program hung). It might be nice to update the GUI periodically. But that might cause contention, with threads waiting for other threads to update (for instance, if I am writing to global variables, I need a mutex, which will block each thread which is waiting to write).
I'm new to threading. How is this normally done? Perhaps the main program could poll the threads, instead of the threads iforming the main program?
With regard to QUIZ questions; Easy - beginner, Medium - intermediate, Hard or Very Hard; I guess we would all like to see an equal balance of such questions, yes? However, my question for beginners and those who consider themselves capable of answering harder questions is, would users like more puzzle-based questions where you have to solve something using either mathematics or / and manipulation of text characters and so on?
This could possibly lead to simple number based games or those games using letters or even both numbers and letters. I am not thinking of programs that would take any longer to run than say 30 minutes maximum or would that be too long? I just thought I would start this discussion as it may help all forum users, especially beginners to improve His / Her own coding skills.

I learn vb6 years ago but very limited. My goal is to get good with serial communications. I have bought the 2nd edition book of "Serial Port Complete".I wrote this code to send and receive data. Very crude yet I know. I'd like to display the number of bytes being sent in a label or textbox so the user can see the progress. Not sure why it doesn't work as I step through the For/Next statement. I send one text position at a time and have set the write buffer to one byte to help but no avail! [code]

but now that im looking at the data this is prolly only useful for simple data. Im wanting to seperate the data from queries into multiple boxes.

I have a module which performs a database intensive process (moves records from the current database to another database) Sometimes it can take a few minutes to run.What is the best practice for providing my user with feedback on the process and the ability to try and cancel the operation?Currently I have recently converted the module to Class which raises events as it progresses. I load a form, declare the class, then call a routine in the class to run the process, receiving feedback in the top level form?

Working on a DragDrop application. I have a class object (built as an object) which has a GroupBox that is enabled for DragDrop.
In the class I have set it up so that the cursor will change when it enters the groupbox, leaves the groupbox, mouse is down within the groupbox and drag/drop is working. I also set up a label in the class object and changed the text in that label as well. Basically, the text changes in the label as expected including 'FEEDBACK' appearing when I am dragging the object BUT the cursor stays stubbornly as a pointer. This is tghe state of affairs either when I debug the class or when, after I build the class, it is run as part of the main program.
Here are the subs set up in the class.
Private Sub GroupBoxSourceMouseDown(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GroupBoxSource.MouseDown
GroupBoxSource.DoDragDrop(GroupBoxSource.Text, DragDropEffects.Copy)

View 8 RepliesI am working in VB. I have a fairly long and detailed explanation that I'll avoid posting but what I'm looking to find is quite simple. I'm looking for information how the command line executable LAME.EXE (the Mp3 encoder) returns information to the host program/form.
I am a VB novice and a novice to programming in general and am looking to learn more about as much as I can on the whole but basically I have a Windows form that gathers all the necessary information as a front-end:
The input .wav file path
The output .mp3 file destination
The encode settings (bitrate, frequency, etc)This information is pooled in to a string like this: lame.exe -v -b 112 input.wav output.mp3 or any variant on the settings selected in the GUI which is then in turn used to execute LAME.EXE with the set of parameters in a command line console...That's all well and good and it is quite functional but what I'm looking to do is to 'hide' the console in itself and have the encoder feed back its progress, say as a percentage inside the GUI.
The problem is that it doesn't appear that LAME in itself has this kind of functionality explicitly built in. I know it's possible however, as every single front end in the world has this functionality.I have tried a few ways of doing this with avoiding the issue of not being able to find the functionality within the codec. Perhaps I'm looking in the wrong place entirely or I'm not thinking correctly 'outside the box' as it were.
what I'm looking for is to use a command like this within the script itself: lame(v,b,112,"C:input.wav","c:output.mp3") or even pass the parameters obtained from the GUI a string formatted dynamically on the fly itself.I expect of course that this kind of functionality won't be available anywhere at all, what I'm really looking for as a workaround that reports the actions/progress/console output of the executable back in to the VB program somehow.
