This one has me stumped. I'm trying to change the location of an object's X position so that it has a marquee like effect. I'm doing this with buttons and text, etc..
PictureBox1.Location = New Point(PictureBox.Location.X - 10, PictureBox.Location.Y)With the intention of it moving 10px to the left. I would then use a timer, but it scrolls automatically for me,
I'm trying to make a program with transparent labels over pictureboxes and when I set the label Parent to the PictureBox the position of the label changes.

I do not know how to do the search of the datatoenter in a listbox with more then one item. If the item is already in the listbox then exit otherwise add it to the listbox.Threaddisplay adds the data to the listbox which I can do when there is no item yet.
I have the following code inside my MDI parent form:For Each crl As Control In me.Controls
crl.?????

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?
I have another question about my customizable Menu/Tool/StatusStrip control.
I have three controls called CustomizableMenuStrip, CustomizableToolStrip and CustomizableStatusStrip. Each of those controls has a property called Appearance, which accepts an instance of a component called AppearanceControl.
The AppearanceControl component basically exposes all color properties for the customizable strips, so the user can edit them, and more importantly exposes a ToolStripProfessionalRenderer which the three strips have to use. This way the three strips are rendered with the colors the user chooses in the AppearanceControl.
Now, I'm wondering if I'm doing things the right way. When any of the color properties in the AppearanceControl has changed, all the strips that use that particular AppearanceControl should have their Renderer set again, and should be invalidated.
I figured the easiest way (and probably the only way?) to go about this was to have the AppearanceControl raise an event (AppearanceChanged), which the three strip controls listen for. When that event is raised, the strip controls can set their Renderer to the Renderer that the AppearanceControl exposes, and then invalidate themselves.

View 6 RepliesI was using this old method of creating a bunch of rectangles when I need to get the location of a certain point within a grid so I could draw images on the grid. The thing is, I don't want to use rectangles, I want to be able to just round the location as if I were using rectangles. I need it to be able to round the point (66,70) to (50,50) so if you can imagine a grid and the mouse position being within that square in the grid, I need to get the location of the upper left corner of that square.
View 5 RepliesI need to create a user control which can be used in my all projects. I have created a user control with a TextBox Control and a ListBox Control. My goal is that as soon as any character is pressed in the textbox, Listbox's item which starts from that character should be selected. I have done all the coding needed for the functionality but my problem is that when I add this usercontrol to my form, I should be able to change the DataSource, displaymember and valuemember properties at designtime. But I cannot see these properties when I add the control on the form.
View 1 RepliesI would like to know if its possible to bind the property LOCATION of an object like button.[code]So that, every time I move either the hscrollbar1 or vscrollbar1 the button1.location will change or moves the object to the location of hscrollbar1.value and vscrollbar1.value. It should happen without setting its value using the SCROLL EVENT.
View 3 RepliesI have a single form that I would like to move across the screen with my VB program. Of course it's simple to set the location X and Y property for compile time using the properties tab, but I want the form to move as the program runschanging the coordinates within a for-next loop.I can easily get the X and Y coordinates of the form within my program by using X = me.location where X has been dimmed as type point.console.writeline(X) will appear as {X=20, Y=40}. for example
View 2 RepliesVS 2008, vb.net, Win7 development machine. I've developed a Windows application with several different forms, and am using the My.Settings feature. This is the first time that I have used this feature. For each form, I have set the form's property binding 'location' property to an entry in 'settings' of My Project settings page of the VS 2008 development environment. The settings are set to user scope.
1.) Do I need to add any code to my application to make the settings work, or is it sufficient that I have the "Save My.Settings on shutdown" set to true?
2.) When I create my setup to install the application, what settings file (app.config?) do I install to the user's machine, and what folder should it be installed to?
I am capturing a few system command messages (namely minimize/maximize/restore). Inside the WndProc override I am trying to change the form's Me.ShowInTaskbar value but it is causing weird behavior in that minimization and restoration does not occur properly.Can anyone think of a reason why changing this property would interfere with this? The reason I don't really want to post code is because duplicating the effect takes a bit of code/setup. My initial thought was that changing the property's value is somehow sending another windows message and canceling the one I am currently manipulating. I realize this is a little vague but it's a shot in the dark.
View 1 RepliesI need some help to understand my options to get this working. I try to update a textbox control by a property-changed event from a class variable. I've digged around for a day and have a vague understanding that this can be solved in three ways:
1. Using some "if InvokeRequired", "Invoke" code in the handler method
2. By programming a special delegate class for this variable
3. By using a databinding directly linking the control (textbox) to the class event
Now.. Are these options correct? And would it be possible to get some help to show these three solutions in actual code (relevant to mine)? I can't seem to manage to sort all the information to a working code. Also, what are the pros and cons of the different solutions?
As my code stands now, it's obviously none of the above, as it gives a cross-thread error, as indicated.

I am experimenting with a transition from my application built in VB6 to vb.net. I know, about time. At the same time, i am making changes and improving upon the original. One area that I am working on is within my employee class. very standard class, nothing fancy. One change I want to make though is allow for an employee to be assigned more than one work location. Employee has (is assigned) Stores. In reading about collections, it appears they are different in .net (as they should be), but I don't know what the sytax changes will be to implement my changes.

View 2 RepliesI would like to be able to set Control visual properties such as color, boarder, flat style, etc. on the base class of the control so that as I add new instances of the control, each instance inherits the visual properties of the base.

View 4 Repliesi frequently have troubles with the dock property. it seems that either the order of creation or adding to the parent control determines whether or not a control's dock property supersedes another's. e.g. a control with the dockstyle fill will overlap with another docked control on the same parent. does anyone know what the rules are to determine how docking will behave; particularly in dynamically created GUIs?
View 2 RepliesIs there a way to bind the text property of a control to an expression? I have a user control that I add to a FlowLayoutPanel. You can see I have 4 controls in the FlowLayoutPanel below. The first control is a LinkLabel and the other three are my user controls which are numbered 1, 2, & 3. I'd like to bind the label that shows the 1, 2, or 3 to the user controls index within the FlowLayoutPanel.
If I happen to remove the 2nd user control I want the 3rd user control to now display 2. I could use the FlowLayoutPanel ControlAdded or ControlRemoved events, but wanted to see if I could do some binding first.
If I need access to the value of a user control's property BEFORE PreRender, would I need to base the custom control off of one of the preexisting data controls (repeater, listview,etc.)?One of my user controls features a gridview control that is configured based on the user control's properties on which it resides. Several of the key properties alter the SQL Statement for the underlying recordsource. I'm now in a situation where the property that sets the WHERE statement for the SQL Statement needs to tied to a value in the user control's parent FormView. Think of the formview as displaying a customer detail record. The user control takes the customer's account number and then displays data from a related table such as Customer Contact Names. Since the gridview is created before the control's prerender event, working within the prerender event doesn't seem efficient.
View 1 RepliesI have a control on a form - I need to know the coordinates of that control relative to the FORM.
Now before I get six replies saying, "Control.Location DUH!!" that only works when the control's parent IS the form. What if the control is nested inside one or more container controls?
Could I write a routine that crawls up all parent containers until I reach the form calculating each offset as I go? Sure! But this extremely crude operation seems clunky to me - What I'm looking for is something a little cleaner.
So far the closest I've been able to come is this:
Dim ClientPoint As Point = Ctrl.PointToScreen(Ctrl.Location)
Dim LocationLeft As Integer = (ClientPoint.X - Ctrl.ParentForm.Left) - Ctrl.Left
Dim LocationTop As Integer = (ClientPoint.Y - Ctrl.ParentForm.Top) - Ctrl.Top
The problem with the above code is: It does NOT take the Form's border or Titlebar into consideration... so this calculated location would be off slightly depending on what kind of border the form has.
I am developing a windows app in VS2008 to be used along side ESRI�s ArcMap. Most ArcMap users will have dual monitors and I would like the user to be able to choose which monitor my app is loaded on to.
When I deploy the app using the standard install package, the app will load onto which ever monitor the user places the desktop shortcut. However, when using the ClickOnce method of deployment, the placement of the shortcut does not matter and the app always loads on the primary display monitor.
Is there a way to control where an app is loaded by code or any other method?

I need to save the controls location and size on the parent form to file.

View 12 RepliesI have a picturebox (pbRows) that I want to always be aligned with the right side of the screen. The form may be wider than this (I have a horizontal scrollbar), but the picturebox always needs to be along the right edge of the screen. Currently I have this code snippet in the form_load subroutine:
Dim rowsX As New Integer rowsX = Screen.PrimaryScreen.Bounds.Width - pbRows.Width pbRows.Location = New Point(rowsX, 25) However, the picturebox is aligned with the right edge of the form (initially hidden off the screen). Am I missing something obvious?
I have a listbox with several list items added. I want that as user click on an item, I should be able to show its property. This should change for different items. For example (hypothetical) : Listbox has numbers 1 - 10. Now when I select 1 I should be able to set property - Name, Lastname, Colour, Age.
When I select 2 I should be able to set - Age, Hair Colour (clr shows), Weight, Date. When I select 3 then - City (combo box drop down), Country, Age only. This way value changes for diff items. One way is to put them in property grid and show them. Though this looks nice but adding/removing items in that is not easy. You need to have a class that refer that to prop grid. Do I have to code for each classes for all values in listbox or is there an easier way to manage items in property grid. If you think prop grid is not the right tool for such an activity then can you suggest something else.
