Allow Certain Characters In Certain Positions In Text Box?
Feb 10, 2010For example I only the second character in each line to be an x, while the 3nd to 10th character must be a hex digit.At the moment I use a Select Case, then check the position of the caret (using textbox.selectionstart) and see if the key being pressed is a "legal" character.Is there a better way of doing this as it slows down on large amounts of text.
This is the code I have at the moment:
Select Case TextBox1.SelectionStart

Changing Picturebox X / Y Positions
Mar 5, 2011I'm trying to make my own clone of space invaders as it's been about a year since I've done any programming, and I imagine this will be a good way to get back into it. The main issue that I am having right now, is that I am basically clueless as to how I go about moving the player on a keypress. I have the code for the keyboard input correct, how to move my picturebox.
Here's my code so far (in a nutshell):
Dim PlayerPositionX as integer
Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
Select Case e.KeyCode
Case Keys.Left
[Code] .....
I imagine I probably messed up very badly on this, but I'm completely lost!

View 5 RepliesNested Splitcontainers: Remember Splitter Positions?
Jul 2, 2008I have 3 splitcontainers on my form. Each splitcontainer has vertical splitter orientation
This forms 3 'panels' which are resizable by dragging their respective splitters.
Each vertical 'panel' is then split horizontally by adding another splitcontainer with horizontal splitter orientation. I now have 3 column 'panels' each of which is split into 2 'rows'
My question is :
In a nested splitcontainer scenario
When a user drags splitters and resizes panels,
how can I remember the last splitter location
so that when the form is closed and reopened,
it remembers the last used positions ?
Possible To Rotate Characters In String By Some Number Of Positions
Apr 12, 2010For a project I need to do a String strX is said to be a cyclic rotation of a String strY if it's possible to rotate the characters in strY by some number of positions, n, such that strY becomes strX. I don't mean rotate in a Caesar sense here but in a left-right (or right-left) sense. For instance, strX = abanan is a cyclic rotation of strY = banana because rotating the characters in banana to the right by n=1 (i.e., by one position), wrapping accordingly, yields abanan. Similarly is strX = anabana cyclic rotation of strY = banana because rotating the characters in banana by n=3.I need to write an application that returns True if strX is a cyclic rotation of strY otherwise the result is False. I'm looking into how to do this, I know it will involve and if then statement and possibly some loops. Is there anyone who can help me better understand what I should do?

Switch Positions Of StateImage And IndexImage For TreeNode
Jan 17, 2012I would like to know if it is possible to switch the position of a StateImage with that of an IndexImage for a TreeNode in a Winforms TreeView? Please refer to the image below for an illustration. The first TreeNode has a stateImage and the second one doesn't. My aim is for all IndexImages to align to the left and the StateImage (if any) to be to the right of the IndexImage. The resulting tree would look something like: I think I have to set the tree DrawMode to OwnerDraw and override OnPaint. I read this msdn link but nothing there was said about drawing images.

Jul 22, 2009This I'm almost certain is an easy problem for those with more experience than me. I just need a routine that trades the places of 2 members of a collection class.

This simple problem has my head spinning because once you remove a member all the indexes change.
Working Out The Point Positions Along A Straight Line?
Jul 22, 2010I have two points (x1, y1) and (x2,y2) and have a straight line between the 2 points, from this I can work out the distance between the 2 points lets say it is 50.What I want to do is increase or decrease the length of the line by a predefined amount lets say 10.So If I increase the line length by 10 (from 50 to 60), What I want to work out is what point(x3,y3) would be at the end of the increased line.Hope this makes sense.I have tried to work out the new point using the angle but it does not work correctly, it does not seems to produce a perfectly straight line and the angle from point (x1,y1) to the new (x3,y3) is not the same as the angle from point (x1,y1 to x2,y2).
This is what I have tried:
:I work out the angle
aAngle =Math.Atan((Y2 Y1) / (X2 X2))

Why Doesn't Picture Box Clear And Get Duplicate Displays At Different Positions On 2nd Click
Jun 13, 2011When btnSetup is clicked, 7 rows with 24 colored predefined rectangles are displayed in the pbColors picture box as as intended. The controls on the first page of a tab control. I would like this display to remain intact when I change tab pages but when I return to this tab page the picture box is cleared. If I click the button, for some reason the group of colors is displayed twice, one after the other, instead of once as intended.

Interface And Graphics :: GetDIBits : Return The Pixel Positions In The Image At Which They Are First Located Adjacent To One Another?
Sep 24, 2008how I could search a given bitmap, say "test.bmp" or a printscreen, for two pixels that are next to each other and that have specified color values? The colors are: &H486596 and &H213D66. I then want to return the pixel positions in the image at which they are first located adjacent to one another. I'm only after the first instance of the occurrence. I wish to use GetDIBits as I hear that it's quicker. So I want to find the first instance where the color value for pixel (x,y) = &H486596 and (x+1, y) = &H213D66.

.net - Decimal.TryParse Is Failing On TextBox.Leave And TextBox.LostFocus?
Dec 22, 2010I have a TextBox in a Windows Forms application in VB 2008 (.NET 3.5) where a user can key an estimate amount. I am allowing them to key dollars and cents, and I want to round to the nearest dollar. The original code had the rounding down when the data was written back to a table, and that worked fine - I have this code in a "Save" routine that fires when the user moves to a different screen or record:
Dim est As Decimal : Decimal.TryParse(txtEstimateAmount.Text.Trim, est)
Dim estimatedAmount As Integer = Math.Round(est)
I decided that it might be nice to actually do the rounding as soon as they leave the field instead, so they're not surprised when they reload the screen and find that 1822.60 is now 1823. So I took the exact same code and added it to the TextBox.Leave event handler. And the weirdest thing happened: instead of the variable est being populated with 1822.60 after the parse, it gets set to -1! What the...?
Debugging the handler shows that the value goes into the parser correctly, and if I do the parsing manually via the Immediate window, it parses correctly, but when I let the code do it, it invariably gets set to -1. What's even weirder is that any number gets parsed as -1, not just decimals, and any non-number gets parsed as 0 (which is correct).
Has anybody else ever run into this before? I tried moving the code to the TextBox.LostFocus event instead, but with the same results. I have no idea what in the heck is going on, and obviously there are workarounds galore for this, but it just makes no sense whatsoever.
EDIT: Here's the full event handler (current behavior for which is to put -1 in the TextBox):
Private Sub txtEstimateAmount_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtEstimateAmount.Leave
' Take any dollars-and-cents amount and round to the nearest dollar

Display Queried Results In Textbox Where Criteria In Another Textbox 1 Form
Jun 21, 2010I have a database I am creating with about 50 users over a network. There are about 6 groups of users and these users are spread across 10 branches. I want to block/allow users from particular forms and views. For example I want branch users forms to be filtered by their branch number but depending on the group they are in they can only see some forms. i.e. 50 users, 10 branches, each branch has about 5 ppl of where 1 is in group A and 4 are in group B. I want all users that belong to branch 1 to see the information they enter, but Group B enter data but cannot approved or delete, and group A can enter, approve and delete. So then. On my login form I have the user type his/her username but the i want LEAVE function to update 2 textbox where I have named GroupName and BranchNo. Basically to run a query and look for the username and return in one textbox that user's groupname and the other textbox the user's branch no. This information will be used to filter forms and block the user from certain controls. This is the code I have so far but still can't figure how to display the results.
