Resize Image From Picture Box To Predefined Size (1080p)
Jan 14, 2012As an update to a program I had made awhile back, I am trying to auto-resize the image to meet the requirements of my application without having to manually do it elsewhere. I already can adjust the quality/compression for disk storage, but I want to resize the image so I can save the quality of the image.
So how do I resize an image to 1920*1080. (I want to check the image first to make sure that the image is in fact larger then 1080p before I resize it.)
I'd really like the solution to work in a DLL project so that I can move my application from the Windows Forms to the WPF UI.

View 7 RepliesCreate A Generic Shared Class That Can Operate On Predefined Classes
Jan 27, 2010I have an interface that i have declared some of the basic internal functions, subs, properties, etc. This interface is then implemented into 3 pre-defined classes. These classes are end-use classes so they dont get derived or inherited elsewhere. I am trying to create a generic shared class that can operate on each of these 3 predefined classes and potentially more as long as they implement the interface.

Create File With Certain File Size?
Jul 14, 2009I want to create an application where a user can create a file which is a certain file size. e.g. Two textboxes, one for Name of file and one for file size. When submit button is pressed, a file is generated from the textbox information. Here is what I have got so far:
Imports System.IO
Module Module1
Sub Main()
[Code].....
However this code is only for text files. I want users to be able to specify a file extension. The file doesn't need to work, it just needs to have a certain file size and a certain name. e.g. I can use this application to create the file Song1.mp3 which is 4567kb. It won't play because it is not a valid mp3 file which is fine, it doesn't have to.

View 5 RepliesWinforms - Usercontrol With Dockstyle Fill Not Correct Size During Form Load
May 25, 2011My main form has two panels, left docked and right docked. The right side panel has two child panels with top dock and bottom dock settings. The usercontrol is added to the right side top panel. My usercontrol has a panel and a label. The panel is anchored on all 4 sides, the label is anchored on all except the bottom. At runtime I create this usercontrol and set it to dockstyle=fill and then I add it to my top right panel.
With everything set to "fill" I expect that when I add my usercontrol to the panel it will take on the appropriate width and height and pass that info to the child controls (labels) inside of my usercontrol. My problem is that this stretching of the size does not happen when I create my objects during the Load event on my usercontrol. Even though initializecomponent has ran for the usercontrol the panel inside of it (4 corners anchored) has not taken the x/y values of the available space. As a result my usercontrol shows up about 50% of the width I want.

How To Create An On-screen Shape (circle) That Has A Fill Color, Which Will Blink Every X Seconds
Jun 8, 2011I need to create an on-screen shape (circle) that has a fill color, which will blink every X seconds (go from fill color, to white, back to fill color). This is trivial to do...BUT... i want to do it in my own class, so that I can instantiate it numerous times passing it unique coordinates for each instantiation.
How do I do it? Can a class have its own "timer control" in it independent from the form? How would I draw a shape from a class?

Convert String To Predefined Variable Name?
Nov 9, 2011I'm programming a basic slot machine in Visual basic, and want to use a for loop to randomly choose the image for each slot, display the image in each slot, and change the slotName variable (so I can check later on which symbols are in the slots) for each slot. The problem I'm finding with a for loop is that the variables and objects for each slot have different names (slot1Name, slot2Name, slot3Name, lblSlot1, lblSlot2, lblSlot3, etc). Is there any way I could have could something like:
currentSlotName = "slot" & i & "Name"
This is the code at the moment, this code is repeated (with different variable and object names), for each of the 3 slots, which is pretty inefficient.
' Randomise numbers and assign images to slots based on random numbers, if the hold isn't on
' Slot 1
If Not held1 Then
slot1Value = Int(Rnd() * numbersGenerated + 0.5)
Select Case slot1Value

Moving A PictureBox To Predefined Locations?
Jan 22, 2011I'm working on a little board game we play here in Jamaica just to see how it would look and as a sort of challenge for myself while on vacation. I'm however stuck on how to make my markers (PictureBoxes - two per player) move along the board.So heres my problem; I have 40 slots where the picturebox can be moved to (eg picturebox1.Top = 324, picturebox1.left=243). Now moving to these slots are determined by the roll of a pair of dice. How can I assign a variable preferably an integer for each slot so when the dice is rolled I can just do a little addition as to where the markers can be moved?

View 1 RepliesSelect Predefined Items From A String In Checkedlistbox?
Jan 25, 2012Is there an approach to preselect the items in checkedlistbox on formload.
1) I have a form with checkedlistbox
2) items in checkedlistbox are "One" "Two" "Three" "Four"
3) i have a string str="One,Two"
at formload i want these items in the checkedlistbox to be selected.
is there a way other than selecting these item by looping through the items in listedcheckedbox.
i.e., as we can get the selected items by using ".checkeditems" property
i need a way to select the items of checkedlistbox from a string or array in single statement without looping.
