I am currently enrolled in the class. My final project for the class will generate random numbers within a range of numbers. For example, if I give the user five text windows to choose whether to input a number OR generate a random number, I will have a button called RANDOMIZE. Unfortunately, I do not know the line(s) of code for the random function.
Im kind of wondering can I fix this? When I edit code in Visual Basic 2008 Exspress Edition it will everytime open after maybe 15 to 30 mins feeze and close, sometimes it unfreezes but not always
Here's the program. there are five categories say a, b, c, d, e, each in a textbox (color blue). There will be a command button say "choose". If i click the choose button, it will randomly choose one category and that corresponding textbox example "a" will change color(color yellow). Then if I want to click the choose button again, the selected category "a" from the first selection will change to gray, then a new category will be randomly chosen without "a" in the list and again will change to color yellow. and so on. So I can click the choose button five times, exhausting the five categories without repeating the category that was already selected.
I need a function to calculate the number of weekdays between two dates in VB.NET. I don't need to worry about holidays. My attempts unfortunately have been futile.
This will go in custom code in Reporting Service 2008 R2.
Project Euler's problem 16:2^(15) = 32768 and the sum of its digits is 3 + 2 + 7 + 6 + 8 = 26.
What is the sum of the digits of the number 2^(1000)?I have been trying to do this problem for a few days now and i just can't figure out how to get vb.net 2008 to recognize anywhere near that large a number. I have seen in other posts that some software like java has the integer type BigNumber or BigInteger but i cant find anything like that in visual basic. I'm running into this problem a lot using Visual Basic. I also can't seem to find any of the standard upper level math features in visual basic such as factorials and a few others that i can't remember but couldn't find under the math feature. any suggestions? (Sorry let me rephrase, any suggestions on how to do this stuff without switching to a different programming language.)
I have a database that has two tables in it. One is a table of items (table1) and the other is the table of current items (table2).On form load I need to generate a random amount of the items from table1 and populate table2 with them. I was trying to do something like this:
In a while loop, I am writing a progressively increasing integer value (between 0 and 100) to the Value attribute of a ProgressBar control, when it disappears from the window in which it resides. I have verified at the time that it disappears that the Min is 0, Max is 100, and Value is a valid integer in range.
How do I disable the background compiler for Visual Basic in Visual Studio 2008?
For my sins, I have to work on a large VB.NET project and it often locks up for 20 seconds at a time whilst doing the very helpful background compilation
I'd rather work blind between compiles and be able to do some work.
I am trying to make a console program in Visual Basic on Visual Studio 2008. I want to ask the user of the program if he wants the premium version or the standard version. If he chooses the premium version, then I want it to say premium in his "receipt" later on and if he chooses standard, then standard in the receipt.
I have Visual Studio 2008 Professional and I'm trying to make it so I can click a button to send the application to the System Tray and then click the icon in the System Tray to make the application come back.
Can anyone provide me a method or sample code to do this?
I need a small app that randomly shuffles a set of preloaded numbers. The shuffling will be visible on the screen and goes on continuously (looping) until a key is pressed and as soon as that happens it will show the winning number.Am using visual basics 2008 to develop the application but my problem is when i start the app and hit a key it will loop through my numbers on the text file and it will also display the event but if i hit a key to stop it will not stop..I was workin on the app but my problem is how to stop the loop and resume on the with a keypress. below is the app codes.

I am very new to Visual Studio Application Development. I'm mostly a DB guy. I used Visual Studio as a Report Designer, not much of an .Net guy though I can understand it. I am now asked to create a .net application and I'm trying to create a "Hello World" starter app. I opened my Visual Studio, click File-New Project and all I see is Business Intelligence Projects and Other Project Types. My step-by-step guide says choose Visual Basic, Windows Forms Application. But I can't see it as an option.
I recently loaded my copy of MS Visual Studio 2008 Standard Edition, with Visual Basic, on to my new laptop, one with a Windows 7 operating system. This version of Visual Studio had been on my other laptop, a Windows Vista machine. When I attempt to run any of my Visual Basic applications which has a MSFlexGrid container on it, I get this error message "Unhandled exception has occurred in your application... The error is: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG). Also,

I have been working on a game development program for a few days now. And have come to a halt on one part, and thats adding a 3D space in the program. I do not know the code for this, would some one please provide something i could use for adding 3D space in my project? for example, i have a panel set up to be the view port in to the 3D space. Now i need to figure out how to program it so you can see a 3D space, click on the mouse and drag and the grid will follow the mouse.Likecreate a grid, i wish to give it a grid of 150 x 150 grid pixles.
vb ...Dim random As Long = RandomNumber(1000000000000000, 9999999999999999)... Private Function RandomNumber(ByVal Min As Long, ByVal Max As Long) As Long Dim Random As New Random() Return Random.Next(Min, Max)End Function
...I am getting a OverflowException. Is it so that Random class can't handle Long values?
I want to create a random number with the combination of the text entered in textbox. Suppose the textbox contains bharani. So now the random number generation is the first 3 letters from textbox and the random number from 1 to 1000. So my output must be "bha876"
I've got a global random type variable, let's call it rRandom.In my code, I generate a random number like below:
Dim iRandom As Integer = rRandom.Next(0, x)
9 out of 10 times iRandom is 0, the other time it was 1. The code isn't on a timer, it happens when I do something (say clicking a button), so the frequency of the code being called is about 2-3 seconds, I say this because I've had similar issues when generating random numbers really fast in a timer, or with a for loop IIRC.X is a variable that, presently, starts at 3, and will decrease until 0, in which it'll return back to 3. Obviously, if X is 0, iRandom will be 0, but it shouldn't be 0 all the time.I'm declaring the variable globally because I remember, again, having similar issues using local variables, idk whether I should be or not.
I was before knew how to code that it will give me a random number! Also i know it was 2 ways i could make it. A range from like 0 to 100 if i want that. And then it draws a random number from that! And i knew another there i could type in the numbers and it draws a random from there.
I've read numerous posts and threads about random number generation, but I havent' run across this.If I generate a bunch of random numbers, the results are radically different if I create a new Random generator for each number than if I use on Random generator for all the numbers. The results are much more consistent and evenly distributed if I use the same Random generator.I would have thought the opposite,because creating a new Random generator each time should reduce the number of random repetitions, if a different time slice is used to create the random number.[code]......
I want to create a Windows Forms Application in Visual Basic 2008. I have created my form already, now I just need to add Caller ID capability. how to do this? Will I need any extra components? If so, where can I get them?
I got one listview, and several items, and several picture box. And i want to make a relationship between picture box and listview.Like select the third item, and the picture box 3 show, select the second item and the picture box 2 show. All this in the same form.
I would like to use MSChart to display a line chart (X-Y plot with 2 array) on visual basic 2008. I am wondering if someone here can share working examples of using MSChart on VB 2008. In my program, I would like to read in 2 pressure array, each as function of time. Then, plot the pressures using MSChart.
the problem is that I want to (SQL) select from a table in an Oracle database, and show the results of the query in the VB application, in a Excel like manner (rows, columns, selectable, etc.). Or in a SQL developer manner. Haw can I do that? Browsed through a lot of tutorials and howtos on the internet, did not get anywhere.
