I like to put my Code windows on my 2nd monitor. But after I close them they always reappear as tabs on my primary monitor. How can I get VB2010 to remember to put them on the secondary monitor instead?
View 1 RepliesI 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 ?

For 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:

I'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

I imagine I probably messed up very badly on this, but I'm completely lost!
I have 20 PictureBoxes named PictureBox2 through to PictureBox 21, where I need to conditionally set the positon of them. I was wondering if there is a more efficient way to set their positions than to copy the code out 20 times. This is what I have so far:
For NextPos As Integer = 2 To 21
Select Case Direction

I inherited a working WCF Web Service with one major flaw - the WCF Service consumes memory and does not release unless the service is restarted. After a half a day of requests hitting the web service, the memory on the server hosting the service climbs to close to 2 gig and is dead in the water.
I'd like to be able to release memory after the web service has received its response but cannot figure out how (WCF is still new to me). [code]...

View 5 RepliesFor 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?

I 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.
View 1 RepliesThis 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.
For example: If there are 5 objects stored in a CList of() collection class, I want to swap item # 3 and #5 (or any pair of indexes), what would be the code?
This simple problem has my head spinning because once you remove a member all the indexes change.
I 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))

When 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.

I'm using RichTextFormat, and i'm using cf to change the color of strings. I have this
Code:
cf22dgreengiant
Its actually like this though
Code:
cf2 2dgreengiant
But the parser thinks that the 2 in his name is part of cf. There's a character, in many different formats (usually ) that will fix it, but I can't remember what those characters are called so I can't look it up. It would be like this, assuming ! was the character. This would make it parse correctly
Code:
cf2!2dgreengiant
So what is that character called? Sorry for the dumb question, but I can't for the life of me remember.
how 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.

so here is what I have. I built a program for myself, it runs great so far. I have it all set up so it remembers what ListView items I put in and all that. But Now I want the picture box to save an image location into a text file then read the text file when it starts up then load the image from that file. I tried adapting the same code that I used for the ListView items but I just don't know enough yet to do that very successfully.

I want to write the lucky seven game with classes. It's easier to do it in a form directly, but we have to do this with a class.
I want to keep track of the users account (this is a class as well). So each time you press the button,you pay 1$ or . If you win, you get the prizes on the central account. So when you quit the game and play another, you play with the updated saldo. i'm not busy with the database, but the label won't change. It gets stuck at -1. When you win, the label gets updated but every time I lose, nothing happens.
