VS 2010 Reading / Loading Controls Size And Location Back From A Txt File
Mar 14, 2011
im toying with an idea based round having controls end user movable at runtime, and having a function to save the current position/location of all the controls, so then i can skip through presets i already made as it were. Ill be using .ini files eventually (just testing with txt files to check it was a valid aproach) I can get all the info i need into the txt file, the problem is how to read it back into the app?

I'm working with ASP.NET and VB.NET. I have a page which contains 5 user controls. the page itself does nothing, it just presents the user controls to the user.
The user controls work fine when I come on the page, or when I refresh, but when I go to another page, and press 'Back' only two of my user controls shows up, and they don't work like they're supposed to!
Short description of the controls:
2 controls which look if the user has to create something and shows an option to do so. (goes to the DB)
2 controls show an overview if needed (goes to the DB)1 control looks if the user is an admin (does not go to the DB, but looks in the securityContext)

I have the Context Menu Options like ( Small Font , Large Font ) based on the selection I want to change the size of the Font in the Controls,Control's Size & location(x,y,height,width). The resize of the controls should not affect the look and feel of the forms.

I have come across a problem with visual studio 2010 & vb.net. i have a few custom controls on the form and few standard controls. When i build the application, the custom controls automatically change size and location. Anchoring and Dock properties are fine. Anchored to Top Left without dockstyle. Even if i fix the location and size in design mode, after i run the application the controls again change back to weird position.

I have been searching for a solution to this but I can't find one. I have played with the anchor and dock properties but they are not doing what I want, so here goes... I would like to place and size all of my controls on my form and then when the form is re-sized during run time (different resolutions, full screen/windowed, etc), have everything just scale up or down accordingly. Anchoring the controls to all four sides of my form re-sizes the control properly but it doesn't move it's location in sync with the other control's size next to it, they begin to overlap each other. Am I going to have to code my own scaling code for each control in my program?

I have the following code inside my MDI parent form:For Each crl As Control In me.Controls
crl.?????
Next
The code mainly used for getting some info from all child forms.I can get all the general property like size, location by crl.size or crl.location. But if all the forms have an own variable like myTxt. How could I get this own variable by this For Each method?

Just started using the Windows Browser in one of my forms so the user can select a photo they need to load. This was surprisingly easy (This seems to be the norm in Basic, if you think it will be hard it isn't and visa versa). What I am struggling with is how to set the default location to 'Computer' rather than a disk letter and directory name. The photo is most likely to be on a card reader or Memory stick so the drive letter is likely to change.
I am guessing the command will be:
OpenFileDialog1.InitialDirectory = ???????

In my user control you can load an image into a Bitmap type, it then displays the image onto the usercontrol. However, it works fine with .gif format images, but when i use .png it seems to make the image bigger than what it is.

I have 2 group box components and both are same size,font,location and visible is false. When i click button2, the groupbox1 won't appear(the group box2 is on bottom n group box1 is on top).
Example:
button1
groupbox1.visible=false
groupbox2.visible=true
button2
groupbox1.visible=true
groupbox2.visible=false
Because i want to show the different,so the location have a little different(actually both are same location). I think my code is no problem. The problem i guess is both component cannot locate at same location?

when I click the Open button a file is opened and its items are sorted alphabetically. to do this I have doubled the size of my list. However, when I click the button again to reopen the same file, the items will ADD ON to the previous open-file event even though I have this piece of lstListboxTwo.Items.Clear()(the correct thing is to clear the previous items and add the new ones)So I think this has to do with the new size of my list..I think that I have to set the list size back to its normal size when re-clicking on the button.

I need to map the location of all the back pixels in an image into some kind of structure. The program later uses the structure to select a random pixel location. It then removes the location, to prevent it being used again. The problem is, there is a huge number of black pixels (close to 40,000) so an ordinary array takes forever to search for and eliminate the "used" pixels. Is there some other "Faster" data structure?

I need to load a CSV file into a set of arrays, and show the output into a listbox, which are associated with other textboxes(labels). earlier i had the names all loading into the listbox, but the values in the label were only correct for the last line in the csv file, not corresponding correctly to the listbox values.
Here's my current
Option Explicit On
Option Strict On
Imports System.IO
Public Class frmMain
Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Is it possible to check a location for a file and if a file exists then create a new file (+1) in the file name? For example if there is no test file in the C:Temp folder then create a test.txt file and if there is one there then create C:Temp est1.txt and if there is a C:Temp est1.txt file then create C:Temp est2.txt and so on?
I was thinking
If Not IO.File.Exists("C:Temp est.txt") Then
IO.File.WriteAllLines("C:Temp est.txt" + 1, vbCrLf)
End If

I'm working on a school project right now and I have everything fine except this one part of the project: "The audit and errorevent logs should be archived if they are larger than 5K and up you need to keep up to 3 copies of the files." I know how to read and write text files just fine, so I don't need help with that. What I don't know is how to archive a file based on file size, or how to keep up to 3 copies of the files?
