I've been designing a Interactive Maths Quiz to test students on the modules they've supposedly learnt, but am having trouble getting the textboxes to display the question as i want them.I need to write things like x3 and x-5 but can't get it to work. To get 2 and 3 i copied and pasted off a word document, and that works, it displays it no problem. I tried the same with others and it just displays a box.
View 6 RepliesWe have a .net win forms application, using .net 3.5. Application runs from a terminal server, users access it with Citrix client. when users run this app memory usage goes higher and hiher and it never comes back. even tough we put objects with dispose and set to nothing also the memory usage is not comming down. it starts wuth 75 mb and goes up to 500 mb. it is a 32 bit application.
how can we find the exact problem with the application. the bahaviour is almost same when we run our development box locally.

We were currently working with our thesis regarding file compression and selected LZW compression. So far, we know how to work on it but we were stucked on how to write a byte.LZW uses 256 and up for the code table because 0 to 255 was used for a single byte.url...Our problem was we don't know how to write a byte higher than 255, s it possible, and read it as it is? Or, different way on how to do it?
View 1 RepliesI have one webusercontrol for Datepicker. When I am using this control in content pages it works fine. I have many controls in content page (textbox, label, etc.). All controls are inside a table. I have placed usercontrol inside <td>. When I click on an image, the calendar control is showing. But that time this calender control pushes all other controls (textbox, label, etc.). I have set the z-index at a higher value, but still it's not working.

I want the total sum entered for (Val(InputBox("Enter sales amount:"))) that is lower than 1200 to go in a TextBox2.Text and the total sum higher than 1200 to go in a TextBox3.Text.How should I go about doing that? Is there a way of doing it in the Select Case area?
Heres my code so far[code]...
I want the average above 1200 going in a TextBox5.Text and the average lower than 1200 TextBox6.Text.
I've tried stuff like; "average1 = average1 + average" and "average1 = total1 / subject" and average 1 = total1 / subject1". But none of it appears to be working.
I want to say the timer count the time the Process is working so that it Counts always higher on a Label with the Text 00:00:00. So it always go higher by 5ms:
00:00:10
00:00:15
00:00:20
00:00:25
and so on.
I need help with my forms developed in vb.net 2008. If I run a form in any machine (regardless of xp/vista or Win 7) whereby the DPI is set higher than normal then the size of most of my forms goes haywire. For example: I am attaching 2 screenshots of my updater program. One screen shot shows program being run in normal dpi and the other one shows it being run in higher DPI settings. In the latter case the form sizes shrinks and it looks so weird. In some other forms the controls go haywire. What should I do to ensure that forms looks ok regardless of what ever DPI a user sets in his OS?
(Note: some texts in the screenshot have been edited to protect privacy).
I'm working with a ComboBox which has 14 items.
Using the following code I got a problem
vb
If Me.ComboBox1.SelectedIndex = 0 Then MsgBox("item 1")ElseIf Me.ComboBox1.SelectedIndex = 1 Then MsgBox("item 2") '...ElseIf Me.ComboBox1.SelectedIndex = 9 Then MsgBox("item 9") ElseIf Me.ComboBox1.SelectedIndex = 10 Then MsgBox("item 10") '...End If
The problem is that after the SelectedIndex = 9 it won't read properly the SelectedIndex = 10, it seems like it consider only the first number (1) instead of the whole one (10). In fact get the same result as if it was SelectedIndex = 1
I am currently working on a program for a higher or lower card game. I have my game set up and in place, however I am having trouble keeping track of the cards that have already been drawn from the deck. I am only playing with one deck and need to make sure that once a card is drawn it is placed in a discard pile and will not be drawn again. I did not post my code due to other students in my class using this forum for their version of the assignment. If someone would be willing to take a look at my code I can send it to you via private message.
View 1 RepliesI've got my program running, but when I start it up on Vista, it does so quite slow. I need it to start up faster, I was fiddling around in task manager to check it was actually started and just taking a while, and I noticed it had the priority "BelowNormal", which I'd like to change.
How can I do this from the registry? I've got it starting up, but how do I add a parameter for the process to be started with a higher priority (I.E, normal, abovenormal, high, realtime, etc., I need to test which is suitable).
I am making a new vb.net project . And 1 thing i have noticed many times is The software that i make in high resoltion computer lloks crap in computers with monitor resoluton of 800 by 600.Is there any way we can create software in standard form which has a higher probability to run in all pc's...I can think of 1 way i guess using monitor height and monitor width from properties and then adjusting form size relative to that

I am writing a serial application using VB .net Framework V4 , where I use a background worker to Read a file and send it to a serial port using SerialPort1.writeLine method. The BackgroundWorker1.ProgressChanged Event handler sub Updates the Line Number to a TextLabel and adds each line sent to a RichTextBox using RichTextBox1.AppendText() method on main form (Form1).
The problem arises at 115200 Bauds (and higher),may be because now the text is updated real fast on the form an unhandled Exception in BackgroundWorker1.ProgressChanged Event handler sub occurs. Otherwise at lower baudrates ex: 9600,19200 etc. Application Runs Perfectly Fine.

So I have this program which I can use to drag files in it and do something with it, and when I run it as administrator, it doesn't let me drag the files in at all, but when I run it normally it does. Is there a reason behind this? And how would I go about fixing it?

unordered text file of 3 columns to assign into 2 arrays. I've been given a graphing component which expects a two dimensional array for a scatter graph for the set of values in the last column.
How would I parse through the list given an indexed array of 215 possible 'zone alarm locations' and if an alarm log list item, of which there can more than one for any given zone location, compare in the two dimensional array any previous value and replace it with the higher valued one? The following are my declarations for the 2 arrays. It isn't clear to me why the array for the scatter data was defined as (999,1) knowing there are only 215 possible x values (alarm zone locations)

when setting a column to identity it will auto increment 1,2,3,4..however if you delete 4 & 5 and then insert another record it will go in as 6.If you do this a lot you end up with huge gaps in the numbers,is there any way to make SQL default back to filling in the gaps and only count higher if there are no gaps?I know I can do it in the application, or even a UDF, I just want to make sure I am not reinventing the wheel?

What would be the best way to retrieve the "i" values from higher levels? Should I store them in an array?
So I have an ASP.Net (vb.net) application. It has a textbox and the user is pasting text from Microsoft Word into it. So things like the long dash (charcode 150) are coming through as input. Other examples would be the smart quotes or accented characters. In my app I'm encoding them in xml and passing that to the database as an xml parameter to a sql stored procedure. It gets inserted in the database just as the user entered it.
The problem is the app that reads this data doesn't like these characters. So I need to translate them into the lower ascii (7bit I think) character set. How do I do that? How do I determine what encoding they are in so I can do something like the following. And would just requesting the ASCII equivalent translate them intelligently or do I have to write some code for that?
Also maybe it might be easier to solve this problem in the web page to begin with. When you copy the selection of characters from Word it puts several formats in the clipboard. The straight text one is the one I want. Is there a way to have the html textbox get that text when the user pastes into it? Do I have to set the encoding of the web page somehow?

I have a problem in timers, I want to display 2 forms each one after 3 and 5, how to do that? I mean when the first form appears, after 3 seconds another one will appear, then after 5 seconds the second will appear. I have a code where someone gave me here but its for message box only, thus I modify it to put a form still does not work. Here the code I put in the timer below:
Private Sub frmblabla_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
tmrnote.Start()
Private Sub tmrnote_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrnote.Tick[code]....
I still have problem when the message box stops, it displays all the forms together. All I want is when the message box stops, then it display the first form then stop to display the second then stop to display the last. The first form must stay for 3 seconds on the screen, then after 3 seconds the second appears then after 5 seconds the last appears.
In trying to test some graphic features, I am trying to get them to display on load so button doesn't have to be pressed. I used the following code as suggested from forum. Message boxes run but ellipses aren't displayed until button is clicked which is what I am trying to avoid!

i have to create a mortgage calculator (I know we have killed this mortgage calculator). Has to display an amortization table to display the list after doing the calculation. Here is the actual assignment:
Write the program in VB.Net (not Web based) and have it accept user input of the amount, term and interest rate. Display the mortgage payment amount. Then, list the loan balance and interest paid for each payment over the term of the loan. The list will be longer than the screen, so use loops to display a partial list, hesitate, and then display more of the list. Insert comments to document the program.
I have created 4 buttons. Calculate, Clear, List, and Exit. The buttons all work, but the list does not. Not sure what i am doing wrong.
