Continue A Program Unless A Key Is Pressed?
Nov 8, 2011
I am making a Tetris program and I have a 2d array 10 by 20 for the grid.I want the Tetris blocks I have created to move down one block every second unless the user presses "a" or "d" (to move left or right) then the block should move left or right whilst moving down.The problem is that I have created a loop for it to delay a bit but then it waits for the user to press a key until it continues the program. So the block will stop moving down and just stay where it is until they press something.I have been told that you can do this in C with something like if keyboardhit or kybd() or something then it will read the key but otherwise it will just skip that bit and loop round. So how can I do this in VB?

I am using the MsgBox Function as a help on my program to notify users of unusable entries in my program. After the MsgBox pops up, and the user clicks on either 'OK' or 'Cancel', the program need to clear the box that the bad data was entered in, and continue with the program. What I am trying to do I guess is keep the program from returning unusable values by informing the user of entries that will return such values. But, where I am running into a problem is in when I click on OK or Cancel, the program continues as if nothing was called as a result of the MsgBox info being thrown.
Here is the code I have so far, mind you that I have used several of the other MsgBox codes to no avail.
I think what I need to do is have a line of code that calls my "textbox.clear" if certain criteria are met. but when I tried this, the program did not return to my GUI, it simply ran with a value of "0" in the "textbox.text" that the clear was called on.

I've written a testing program where my students write a test and the results are compiled in a text file. The text file is then emailed to me using SMTPServer.send(MyMailMessage). The program works, except that it takes a number of seconds for the email to be sent. The user clicks the next button, which should bring him/her back to my login screen for the next student, but instead it hangs while sending the email. How do I get it to do the emailing in the background, allowing the person to continue using the program?

My Application (Vb.net, Access 2003/2007) is to scan Access Database files for activex controls and to generate report accordingly.Problem:
Getting an error like:"Insufficient memory to continue the execution of the program."
The above error occurs while scanning for older version of Access files like prior to office 2000.
And the line of code where I get this is as follows:
Dim oForm As Access.Form Dim oAccess as Access.Application oForm = oAccess.Forms(objForms.Name)
But it opens the file and form as well.
Whether it is possible to read the file (Access Forms and Reports) or not?

When I do the try/catch method in my vb.net project I will try the code I want and when it can't do it, i make a message box right after the catch method. The thing is that it will show the message box, and then another message from the program itself. Like for example, I have here a MySQLException, and when i click ok on the message box, it will show another one right after showing the exception itself. How would I be able to get rid of this so the user doesn't have to see this, and the program can continue.

I use this code to send an email through gmail account but the thing I want to do is, I want to check whether the given email and password exists or not and if it exists then pop out a text box with the body of the mail and type the text and then send it as a mail. But in the above code you have to log in and type body and when you send the mail , It verifies for the email and password while sending and if anything goes wrong says there is no such gmail account.but i want to check it whether the email and password exists or not, when the user enters the email and password at the beginning itself.So that he enters the right email to log on to compose a mail.Is there any way to check whether the given email and password is correct at the beginning only ?

I was observing my programs process in the task manager and noticed each action made to the program made the memory continue to rise. So I added a Garbage Collector and since it's my first time using it im not sure if I implemented it right. I haven't gotten any errors but I ran some tests I would like to go over with everyone. After adding the GC I was able to notice a change in the memory my program used- it was reduced.I added the GC to the main forms formClosed event of my application which is used in different scenarios. I also added it to the panels paint events before I tested the program. And noticed a quicker reduction in memory. The Form i mainly use called frmLine1t5. This form calls to the database based on which line to test. Then the form sets the controls that were added in design view to be enabled or disabled based upon the product for that line. This process was easy to implement.I Load each new frmLine1t5 to a collection of the form so people can run multiple tests using the same form. This helped so i didn't have multiple forms for the same type of process. I had to access the forms through a collection so I knew which controls to populate to the correct instance.
I noticed during my testing that I can not add more than 50 items to this collection. The problem is that I remove the key from the collection upon form closing, so I dont know why it has gotten to 50.The test I made Runs two timers. Timer 1 is set to tick every 4.5 seconds This timer loads a new form and tests a new line of product.Timer 2 ticks every 5 seconds and closes the previously opened form.I have it get the GC Total Memory upon loading the form of frmLine1t5 and upon closing the form of frmLine1t5.the results are shown in the picturesThe errors i have gotten occured when ChildForms Open: had reached 50Here are the errors:
[code]...
Possible Causes:I think that upon Form Closing it is taking longer to finish closing before a new form is loaded... But isn't vb.net suppose to finish any unfinished threads? Even if the program is single threaded?And because the form closing isn't "happening" then the key is not removed from the collection.

In my program, if something goes wrong an ErrorForm is supposed to show up and tell what was going wrong.
And if the error is a "fatal type", then I want the program just display the ErrorForm (which gives some information about the error), wait for a button press, and then close the program (terminate run).
In case of error, the form is displayed.. That's good.
But as the program is supposed to terminate after showing the error form, the error form disappears immediately after showing up (so it doesn't allow the user any time to read what's going wrong).
How can I make the program wait until a button press (on the error form) and then terminate?

I've been trying to figure out a simple keypress handling event.I have the code working fine after hunting for a couple of days on the net but have a problem getting rid of the obnoxious bong that comes along with hitting the ENTER key.I've attempted some solutions on the web about changing the KeyAscii to 0 but under that method I cannot even get the program to recognize the key is even being pressed.The code I have so far is as follows and I'm just trying to get rid of the audible bong.

i have a program called Vip Task Manager.This program lets me set up task which others have to complete.When they are done with a task they have to mark it "completed" and make a report on what they have done and used to perform this task.Vip Task Manager has a button which directs them to an upload form, now when they press the "open" button I would like this to happen: Open a certain report making program I made myself.When they finished writing their report and press save, the program saves this report on a dedicated network HDD (.txt file) and closes itself.Then add the file or link to the upload form in Vip Task Manager.What it all comes down to is that they dont have to minimize Vip task manager, open the report making software, save it, go to vip task manager, press upload, press open, look where this file is saved, select it, and upload it.now, typed in red is whats already been taken care of.The rest, I have no idea where to begin to be honest.First I want to find out how to retrieve that a button is pressed in a existing program. (dont know which code it is written in and it is not open source)

I�m having trouble with my VS. It gives me the error "insufficient memory to continue the execution of the program". This is a dangerous error because I cannot save the project either. So all work is for nothing. Actually VS destroyed my mainform at one time due to this error.
Now there shouldn�t be anything wrong with the computer or the project. The computer is new and with ok performance. The program runs ok on other computers (up to 5 yrs old) both published and in debug. On the old computer I use VS express, on the new I have Pro.
I think it has something to do with the graphics (I have added one or two pictures to the project since testing it on the older computer). VS graphics really doesn�t work like it should.
I have a mainform (the one that got destroyed) which I want to use as a MDI container. I want to have a picture as background. That doesn�t work (!) so I use a picturebox instead. When showing childforms the idea is that som part should be transparent, thus showing the MDI�s background.
In debug, as well as after publishing, the result is the MDI shows, and it actually has the picture as background. However the childforms don�t show at all. They show up in the window toolstrip though. Needless to say I cannot save the project because of the memory issue.
So, am I right in assuming that VS cannot handle a simple .bmp picture, or what should I do to be able to continue developing?

How do I do this. I have some long SQL statments and it would be easier to break to another line, but I can't seem to do this. The statment below gives an error.

I have a 'For Each...' loop in the VB.NET code for one of the pages on my website. There is also a Try/Catch block within this code that currently contains an 'Exit Sub' in the event of an error being trapped. However, what I would actually like to do is to merely exit the current loop value and recommence the loop at the next value in the sequence.
How can I do this?

When you are putting in a long string of code it doesn't all fit, so I want to know if there is a way to continue that string on the next line. I believe it's something like & _ if I'm correct in thinking. But I'm not perfectly sure, I guess the question I'm asking is if you can continue a string with & _ or if it is something else.
