Switch Positions Of StateImage And IndexImage For TreeNode
Jan 17, 2012
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.
i'm creating a game like text twist. that when i press letter a, i need to determine which picturebox contains letter a and display it to different location. that also goes to the proceeding letter a's. for example, i have a jumbled letters "aamba". in my code, it only gets the first letter a and removes it form the screen, it's nowhere to be found. and it won't recognize that i still have other letter a's i'm pretty sure about the location that i set it to be placed.here is my
(it's kind of brute force i think) ElseIf e.KeyChar = Chr(97) Then counter1 = 0[code].....
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: Select Case TextBox1.SelectionStart Case TextBox1.GetFirstCharIndexOfCurrentLine + 1
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 [Code] ..... 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 Case 1
how i could get the icons positions i made some code to get the file names and everything but wanted to know how i could get there positions! also i found some codes with google but most of them where in vb6?
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?
i am working on an examination system. the system has to compute the grades and position of each student per stream and per class.each class has got 4 streams. I save the studentsmarks in the database. i want the system to determine the positions of students and the position of each student to appear on the rtf.. report, for example:
I 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 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 am making a game that is similar to Dance Dance Revolution. As you know, there are moving arrow keys, but when i run the program, only one arrow moves up in a loop. I don't understand what is wrong with the code. Also, the score is messed up. It doesn't add or minus points. Code: <!--c1--> CODE
This 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))
I dont want to be setting the index positions and lenghth to a specific number becuase when i choose a different name from the listbox that is at a different position or longer it wont display it properly. explain to me another way around this so as it will allow any details to be selected and read???
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 trying to add a treenode to a listbox... say the TreeNode is named "Blue", when I add it to the listbox with Listbox.Items.Instert the output it gives me is "TreeNode: Blue"... How do I do this without having it bind the "TreeNode:" part to the output?
I'm writing a bit of code that I want to populate a TreeView, which it does quite successfully, but I also want to put a Dictionary in the Tag of each Level 1 child node. Once the Tag has been set to the Dictionary, is there any way I can modify the dictionary, without redeclaring the Tag.For Each verse In Verses
Dim _verse = verse.ToString.Trim Dim _node As TreeNode = New TreeNode(_verse.Split(vbNewLine).First & "...") _node.ToolTipText = _verse[code]...
I need to grab the TreeNode that's selected when someone right-clicks on it. The TreeView.selectedNode() returns the top-most node, and disregards the child nodes.
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.
I'm confused regarding the MS examples for inheriting a treenode. I have created the following class to allow an addtion description field on the treenode:-
I have some code that allows me to drag a treenode into a listbox and then drag it back into the treeview as needed. When I drag a node out of the treeview, the node is removed from the treeview. When I drag it back, I need the node to be inserted into the same parent node/position it came from. I think I can save the node's FullPath property before removing it from the tree, then decipher it again when I re-add it but am looking for a cleaner way
I start with VB 2010 since a short time.I need to check in a Treeview if a node has children or not.In VB 6 there was the property clildren that allow to understand this.
I built a treenode to be populated from my network drives, from this treeview I would like to populate another treeview to show the files when the first one is selected. For example, if the user were to click on the c:TestFolder then the second treeview would show the TestFolder, all sub folders and files.
Below is my code: Imports System Imports System.IO Public Class F_Treeview_Demo Public IsSomethingChecked As Boolean = False Private fbIgnoreClick As Boolean = False [Code] .....
