Panel On A Main Form Containing A PictureBox Control On Top Of A TableLayout Control
Mar 15, 2010
I've got a Panel on a main Form containing a PictureBox control on Top of a TableLayout control. Both the child controls have their docking properties set to Top. The Picture control has sizemode set to Zoom.
What I'm finding is that the picture doesn't size properly when I start the app. There is a border at the top and bottom in the PictureBox control. It's only when I resize the overall form that it's correct.
So at the moment I've got this ugly bit of startup code, just to fix the problem Me.WindowState = FormWindowState.Normal Me.WindowState = FormWindowState.Maximized
What am I missing?

I am looking for a way to be able to use the tab control on my main form and transfer all 3 other forms onto that main form that has the tab control. Problem being is that some functions are named the same in each of the septate forms i want to bring into just one for the tab control.Is there a way to separate the code for each form ON the main form of the tab control so i don't have to rename/recode each of the 3 forms i want to place on the main form of the tab control? [code]so when i put both form1 and form2 code on the main form where the tab control is, its going to tell me that i have a duplicate function name.

What I'd like to do is in my application move a control like a groupbox or frame with content on it from e.g the main form to a tabpage on that same main form using code.
I can change the position of the control using it's location, but I haven't got a clue on how to move it from the main form to a tabpage, or from 1 tabpage to another.
-Is this at all possible and if so, how can it be achieved?

I have a windows application with a main form, on which a user control is added dynamically when a device connects trough USB.
On a user control, there is a thread wich is getting data from the device trough USB and when it is finished, I want to change a progressbar that is located on the main windows form where user control reside.
This is the code that is I call on the user control thread to change the progress bar value:
Frm_Main.UpdateProgressBar(CInt((AllBytesReceived / MaxBytesInFlash) * 100))
and this is a code that is called on the main form:
Private Delegate Sub UpdateProgressBarDelegate(ByVal value As Integer)

I'm trying to make a label control transparent over a Panel control.However by setting the background colour of the label to Transparent, it actually sees right through to the form itself, not the panel as intended.
As an example we use a panel with a background as white, we make the label transparent, however it gets the form�s colour as blue.However, we are using a custom panel control and need the label to be transparent over the panel and not see the forms background.

I need to quickly demonstrate a project and decided to create a user control that is connected to an Access database through pure simple data connections (create the dataset and drag it on the control.)When I build the project and add the usercontrol to panel control on the main form, no data is shown in the datagrid.When I add the data components directly on the main form, the data is displayed properly. why I can't get my databound user control to display the data on my main form?

I've got an app that I want to have an MDI with. It functions fine, but there needs to be a control panel off to the side of it to drive the child documents' creation. I have two problems with this.
First, if I add the control panel to the side of the form, it just overlays the MDI portion of the form and the children will spawn behind it. I can more or less manage the positions of these children, but the problem comes when I want to minimize the children, they minimize behind the control panel and I don't know how to move them. So I need to shrink the area they can move around in. I've read in places that you can use the splitter object, but that never seems to cooperate with me and only wants to move to the extreme left or right of the parent form. How can I reduce the area the children get to interact with? I've tried creating a MDI Panel, but VS has a fit with that.
Second, I've got a datagridview holding the data that will spawn the child forms. This is working well, but even though I've set the rows to be not resizeable, I can still make them grow or shrink during run-time (not programmatically). How do I stop this?

In the user control, there is RichTextBox1's TextChanged event, I want it to set RichTextBox2's Text to the same as RichTextBox1's Text, I'm currently using: RichTextBox2.Text = RichTextBox1.Text. The user control is on the main form, when I run the application and type I get this error: StackOverflowExecption was unhandled. [Code]

In VB6 I could embed a panel or picturebox containing controls or images within an outer panel or picturebox. If I moved the outer control then the embedded panel would move with the outer panel and stay in the same relative position, which is what I require. This doesn't seem to happen in VB.NET, the internal panel stays fixed in its location, even if I have pasted this panel within the outer container. Is there are trick to this or do I have to code to get the internal panel to move with the outer one? How does an internal container remain embedded within an outer one?

I am using multiple forms to create the interface for an application. The main form of the application is the only 'form' used. I am kind of stuck on how to copy the controls to a panel created on the main/different form.UC1 is a public usercontrol, so I don't have to reference every control individually later. mp3ctrl is a public control variable.[code]I have Listbox1 on mp3form. I created a new instance of a transparentlistbox control I have in Form1_Load. When trying to set size/location to Listbox1.size/.location, I get the error of Listbox1 not being declared/inaccessible.I thought by creating new controls on the main form and setting the properties, I could reference the control through the .name, especially since the control has been added to the main form.

My name is DN and I'm creating a strategy game. I have created a panel and I have put a PictureBox on it. Now, the problem is here: The PictureBox is bigger than the panel. I know that we can solve the problem with putting to the panel two scrollbars, but as in a good game scrollbars should not exist in the main picture (map). I want for the people to control the map with keys (up,down,left,right) and the scrollbars should not be visible.

I need to plot some analog values read from the serial port.I plot them in a picturebox starting from left. When I reach the end of the control at the right side I shift all values to the left of a point and I plot the new point at the right, (I have some flickering but it could be acceptable). This is my plotting control.My problem is that I have to clear the control (picturebox) in order to plot the shifted graph, but the method Clear of the Graphics class clears everything inside the picturebox, even my grid.How can i make always visible a grid "in" my picturebox?
1.a transparent image with a grid over the PB? (the clear method cannot remove it)
2.an image with a grid below the picturebox that must be with a transparent background to make visible the grid?
3.multiple layers on the same picturebox?

I am currently working on a program in VB that is 480,600 and am using a panel with a picturebox inside of it so that I can use scroll bars to view a chart in the picturebox since my form will be so small. Since viewing a large chart is pretty irritating using scroll bars to some, what properties can I enable or disable to get the panel and picturbox to expand also when the Form Maximize button is clicked rather than staying the same size up in the top corner?

The following code works perfectly to allow moving a control on a form at run-time. However, when AutoScroll is set to True on Form1, and you drag Button1 past the right and/or bottom bounds of the form, it goes haywire. I really need someway to smoothing control the autoscroll so that as you scroll the control off the form, the scrollbars smoothly appear.
