I've got a form that opens up whilst data is being pulled from the database in another form (basically a box to say it's loading), the form opens when I want it to and the gif shows but doesn't run until the code on the other form has finished.
View 5 RepliesI'm currently trying to write a football simulator but am having issues with the computer becoming unresponsive. There are long lines of code (several thousand lines) that are executed over and over as one run of the code is equivalent to one second of game time. While the game is setup to be like Football Manager where you watch the game live, there will also be cases where the entire game is simulated without you watching. When doing a full sim of a game, I just have a loop which executes the code block 7200 times (games go for two hour roughly).
At the moment this takes about a minute but even when I get it down to the desired 5-10 seconds or so, I dislike the fact that the computer becomes completely unresponsive during this time. In a round there are 9 games and you'll be simulating without watching 8 of them. You're looking at 1-2 minutes of simulation time or possibly more. I can't have a loading screen that long! How can I program the game so it runs these simulations yet the game still remains responsive? It'd be fine if the user could muck around in the menus and stuff while the simulation runs.
We have a purchased application written in Visual Studio 2005 that uses tab controls for displaying information. One of the tabs is for reporting and I am trying to run some code to enable and disable a Validate button. It has a proprietary report component (LxReportView1) that is initially disabled. As user enters information, the Validate button is used to check for required fields. After data entry entries have been validated, user click Validate one last time and record gets flagged as validated and report component (LxReportView1) gets enabled for use. Ideally, whenever this Report tab is clicked, it will run my code EACH TIME.[code]Works fine when user's first action is to bring up a record that has already been validated. So when user clicks on Report tab, report component LxReportView1 has been enabled for use and the Validate button has been disable just as designed. Problem is that given a list of records, if user selects a record that has NOT been validated yet and then later on brings up another record that has been validated, code does not run. How can I get this code to run EACH and EVERY TIME the form loads.
View 4 RepliesI have an application which uses hotkeys which are to be defined by the user. It is a combination of 2 keys, either CTRL, ALT, SHIFT as one hotkey and the F* Function keys as the other (e.g. CTRL + F1, ALT + F2 or SHIFT + F8) As stated these are then chosen by the user before a global keyhook is put in place to listen for them and trigger an event. In my app I have all my function keys as follows:
Public Const VK_F1 = &H70
Public Const VK_F2 = &H71
Public Const VK_F3 = &H72

I have a form which I use to read data from a text file and export it to an excel template file. The data it reads is constantly updated so I would like to add a check box to cause the data to be read every 10 seconds. It's set up so the user can either do one quick scan by clicking a button, or they can click the button while also having the check box checked and it will scan every 10 seconds.The problem is, once I check the check box, I can't uncheck it. I have created a greatly simplified version of my original code to demonstrate this concept.

View 1 Repliesin my program it has a log in system already done by myself and once logged in you can do whatever i have coded in if you understand my meaning . what i want to add to it is a timer that can be edited that runs as a standby timer like with what a screen saver does and logs out after inactivity for a specified time now i have no idea where to stat with this so if some one could put me in the right direction or an example would be great.so i need it to start a timer once the mouse is not moving and no keyboard keys are being pressed and terminate the timer once keyboard keys are being pressed or mouse is being moved it's for an update that i am releasing on my publishers website for my program?

View 4 RepliesFormA calls DialogB where user cancels DialogB which exits via ForceTermination(), see insert.Caller FormA check for DialogResult not = OK, which it isn't, and I can see this in debug as Abort(3).However, the code continues merrily along its way until I get a 'null reference' error which I'm trying to avoid via Force Termination().This is caused by the user cancelling DialogB, a selection process to get a database (SQL) instance.[code]

View 7 RepliesI am starting to learn visual basic. So far, it is quite simple and easy to use. I am liking it!Anyway, I want to make applications a little bit more complex.How do I open a new window (form)? Maybe I click a button on my main form and another form pops up.How do I"deactivate" the main form while the new form is running? (if I try to click the main form, an error sound plays)So my second form has a text field and a "OK" button. If I click it, the second form closes activating the main form again. I want to "pass" the text in the text field from the second form to the first one. How do I do that?
I had a project converted from vb6.. now I'm replacing old controls with new ones.. but when I delete the control off the form.. the form generate code still shows it.. I didnt think I was supposed to monkey with that code and remove anything..
I assume there is a way for the code to regenerate from the actual form design ?
I tried rebuild project.. but that didnt do anything.. I'm a tad new to vb.net..

Firstly I want to state this doesn't affect the usability of my program. I made a GUI for an old cmd line program and when running the GUI's form will freeze up and be completely unresponsive. This is annoying since you can't move the form and if you open something over the form then move/close it you get the affect in the attached pic. Attached pic is the program running and the windows calculator being moved around over it.
Is there a way I can have the form stay responsive while the program is running? I don't need for any of the buttons, text boxes, etc to be editable while the program is running.
I'm developing a VB.net windows form app in Visual Studio 2010. I want to be able to drag the form to another location or minimize it while the app is running. Is that possible? Here's and example. I have a form with 1 button. Here's the code associated with the button:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim time0 As Integer
Dim time1 As Integer
For time0 = 0 To 1000000000
time1 = time0
Next
End Sub
I can move the form or minimize it until I push the button. Then it freezes until the code stops running.
what i currently have is the main form that then when a user presses a button it runs some functions that loops through some files and changes them and then copys them to another location the functions can take quite some time. what i want to is when the button is pressed it opens another form with a textbox on it and when it has finished 1 cycle of the loop is outputs a line to the textbox and tells the user weather or not it has been sucsessfull.
at the moment i have:
Dim t As Threading.Thread
t = New Threading.Thread(AddressOf Form3.Show)
t.Start()
[Code]....
On my program the user clicks a button which then runs the main code for my program. The problem is once the code is executed I can no longer move or interact with any form boxes, reliably at least . Sometimes there will be a period of delay where I can move it for an instance. Is there anyway I can make it so that my form is able to be moved while the program is running?
View 3 RepliesI have form1 and form2. A button on Form1 calls a thread background process (below). That process processes the command and when its done should close form2. I'm opening form2 within the current thread but trying to close it in the background thread. This is because if i close it in the current thread it closes immediately. I included the 2 functions below and what I have tried in the inline comments. Form2 is a simple form, basically just an animated gif. It is to show the user that something is happening(like a status bar) then close when its complete. I tried running different priorities instead of different threads but due to the results threading seems to behave the best. I'd like to keep access to both forms during the process, the pc, and screen refreshes realtime.[code]

I have created a porcess that manipulates large volumes of text. I have created a form that has a button that manually starts the process. I have tried to give some feedback that the process is actually progressing through the data by changing the value of text fields on the form. However the text fields do not update on the form until after the process is complete. I had this working in another program but cannot figure out what I am doing different.I use the following code to change the text.[code]
