Make Loop To Make Certain Thing Happen About 10-30 Times Without Taking In Too Much Memory / CPU?
Oct 16, 2011
A few years ago I have been busy creating this application but it didn't succeed, now Im coming back to it and similar problems occur. Basically I use SetPixel on a given window to draw a line, work fine, but the line goes away as the window redraws itself.The problem: I have been putting timers and threads on it to make sure the line is being drawn. Is there any way to make a loop to make a certain thing happen about 10-30 times without taking in too much memory/CPU?

what MSDN is trying to indicate here on this tutorial, ref this page: Walkthrough: Creating a SQL Server Express Database.I cannot make this happen in VS2008 SQL Server 3.5 ? To create a relationship between the tables created in the previous step 1.Right-click the Database Diagrams node in the SampleDatabase.mdf node in Server Explorer/Database Explorer and choose Add New Diagram.
2.Click Yes if a dialog box opens asking to create the required database objects for diagramming.
3.Add the Customers and Orders tables to the diagram.
4.Close the Add Table dialog box.
5.Drag the CustomerID column from the Customers table onto the Orders table.
6.Verify that the Customers table is the Primary key table and the Orders table is the Foreign key table, and verify that the CustomerID column is selected for both tables.
7.Click OK to close the Tables and Columns dialog box.
8.Click OK to close the Foreign Key Relationship dialog box and create the relationship.
9.Select Save Diagram1 from the File menu.
10.Leave the default name and click OK.
11.Click Yes in the Save dialog box.
I can create relationships but not the Diagram ?

i was wondering if theres a way to make an if command apply to more than one thing, this is my problem: theres 9 white squares and if theres one or more thats orange, then a numer.text goes down one but at the moment theres 9 white squares and for every one thats orange the score goes down one, so if three are orange then the score goes down by three, or if five are orange then the score goes down by five, I'd like to make it so that even if there all nine the score only goes down by one.

I want my application to be able to communicate 2-way between the application on another computer and the host server which will be running on my computer.I want to use the BackgroundWorker built into vb to create a thing to make it listen for incoming messages, and also send out messages to the client.The client needs to listen and receive, same as the server, because both need to communicate with one another.I do not know how I can make it do either sending nor receiving.I would be using two different background workers to keep the code seperated and organized so that I will understand what code is for what.
I want the code to say that if i receive the message "Apple" without the "" and cap sensitive, then it will change Label1.Text = "That worked, word received Apple" or something similar to that. ( This is because I am ignorant and I want it to interpret the text sent through to figure out what the application is supposed to do, and last time I couldn't figure out how to make it do something when a certain text was received.

Starting a few weeks ago, compiling a project (VB.NET, .NET 2.0, VS 2010) has taken several times as long as before. In Task Manager, I noticed ResXtoResources.exe taking lots of CPU for a while. I've finally been able to get some data on this using MSBuild's 'Diagnostic' output setting, and comparing that output to what I see in a branch from a few months back. Most striking are the final lines, which give timings. Before:
Target Performance Summary:
[..]
1395 ms CoreResGen 1 calls
1930 ms CompileLicxFiles 1 calls
2135 ms GenerateApplicationManifest 1 calls
2844 ms CoreCompile 1 calls[code].....
Both projects were compiled on the same system with the same settings. We've made numerous changes, to be sure, but nothing to the order of magnitude that would justify such a change in timings (and only for this one task!). I assume resource generation is getting stuck on something — a circular reference, a missing one, etc. I have been unable, however, to find anything useful on how to trace such a problem down to what I assume is just a single resource file.Short of looking through thousands of checkins or temporarily removing some forms (and thus, their resource files) from the project, is there anything else I can do to figure out the issue? I can't seem to find individual per-resource file timings.
Findings so far:I've created a new, empty project with all the same .resx files in place.The issue is not reproducible in .NET 4.0: compiling the exact same test project takes less than a second.The issue is reproducible in .NET 2.0 as soon as I also add one of the forms from the original project; apparently, it will otherwise not compile the resources "properly".Removing individual .resx files will reduce the timings 'proportionally'; that is: I have unfortunately not found a single file that is the culprit.

I have VS 2008 and wow is it different from the old VB I used about 10 yrs ago! What I am trying to learn is how to create an ap that has a window that displays elapsed time like a stopwatch. Then I would like to be able to click a button to pause that time and start another timer, and then have yet another button to reset all. I have the form designed using a RichTextBox but am not sure that is the best way to display the times.

How would you make the Interval of a timer to be between two times.
E.g if you wanted an event to occur between every 7 and 20 seconds?

I am constructing a program, i am new to Visual Basic, but i have past programming experience. I was wondering if anyone knew how to form a loop that could...lets say calculate the answer when two numbers are added together,and it would repeat this thousands of times, etc. And if there is a way, would it be possible to calculate the time taken to complete this loop.

I would like to know how to make a button click only so many times until it becomes disabled.
I would also like to know how to keep what is put in a RichTextBox there, without erasing the other text;
Example: Two buttons, the first puts "1" into the RTB, and the second puts "2" into the RTB. However when I press the second button, it over writes the first value.
How can I prevent this?
You Can Ignore this question below;
Old Question: I am working on a counter, and want to know how to make a button show itself if I hid it.
I have:
CODE:
And would like to know how to make one of the buttons visible again, with one big button.
I know it has something to do with an "If" statement.
Answer: Button#.Show()

I'm trying to make a form that takes user input 3 times, and each time compares it to the correct Answer... which is an array of {"C", "D", "A"}.Each time the user's input matches the correct answer ("strCorrectAnswer()"), then I'll add 1 point to intUserScoreCounter. I'm wondering why this code is returning an error (hilighted in blue)? Can I not compare a String to an Array?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEnterAnswers.Click
'Handles Enter Answers functionality
Dim strCorrectAnswer() As String = {"C", "D", "A"}

I am trying to make a timer that beeps 3-5 times and runs a progress bar. All it has to do is click start (timer set for 2 minutes starts) and as time runs out the progress bar fills. When the time is up 3-5 beeps happen. I am missing the coding for the 3-5 beeps and design parts for it and all coding for that along with code for setting the 2 minute timing. There is no label for telling the time left or to go just a progress bar. Here is my code so far.

I need to know to limit the number of times a radio button can be used. Maybe the number of times the radio button has been used can be stored in an XML file, and when the user wants to reset the counter all they would have to do it delete this file. I really don't know, that's why I'm asking you. But,the program will append a string every time a button is clicked with a radio button selected, I just need to know how to, for instance only allow RadioButton2 to be used in this manner say... 15 times.
