in a ordinary form I added a label (Label1) and a button (Button1) with the followiing handler. Well if I press Button1 my dot dashed line is correctly drawn over Label1, but what I need is that program automatically does it on form
load.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Graphic As System.Drawing.Graphics

I have managed to develop a form which allows me to add a record to an access database using Adonet. The last few fields added are populated when i place the mouse over a floor plan image on the form (provide geographical location) and capture the x y coordinate. Prob im having is how on another form i get the points to automatically re-draw on a form with the same content (floor plan on it. I can obviously retrieve the data set using a data adapter/data table just cant make it draw on top of the graphic automatically.
View 1 RepliesOn Form1 we have: TextBox1 TreeView1 - holds list of customers, is located near the bottom of the form, not visible from the start. Now, when I start typing text in TextBox1 (i need to filter customers), TreeView1 appears and suggest for example 30 customers matching the searched text. I want the program to show the treeview and draw it also outside of the Form1 boundaries.
View 7 RepliesI've got a usercontrol that's a simple rectangle with three labels on it. It's essentially triggered to give a caption to an image when the mouse is moved over it. As I feared, adding the control to the form (or any container on the form) restricts drawing the control to the region defined by the container. I tried increasing the region of the form and the container, but it still didn't draw outside the container.
So my question is: Is there a way to make the control display partially inside the container/form and partially outside it, or is there a better object type that will do what I want?

I need to get the DataGridView to perform the way it should perform. I'm new to the .NET environment, but I learn fairly quickly. However, I find it difficult to decipher themassive black box of the DataGridView control enough to make it do anything other than what it already does--Draw very slowly.
View 3 Repliesjust wondering if it is possible to have a form and then load up a control on that form but so it runs in a different thread to its parent... i tried:

But it still seemed to be running on the form's thread And just so you know ctlMTTest is just a control that has a button on it, that, when you click the button, a loop runs.
I dynamically load a user control in a form (Form 1).
In my user control there are two things :
a Textbox (TxtBox1) and a Command Button
WHen the button is clicked, it opens a new form (Form 2) Form2.ShowDialog()
My question is, in Form 2, how can i set a value to TxtBox1 of the user control?
I been have some research to this forum about the layout setting save & load...one of the method I found is store it to XML...but it only allow to store textbox value, other like textbox location, size is not work.... it can store every control like textbox, button, label, listview and etc in my form include size and layout and allow to load it?
View 3 RepliesThe problem I am having is that when I make a Paint sub (I have another form adjacent to the one that I am struggling with), when I move one form over the form that has the graphics, it repaints it. This gives me a different result each time, since when it is on hard the grid changes. I would like to know how to paint in the load sub, so this will not happen anymore.

The insertion part of the form works great. But my problem is in the form load part......If i leave a field blank(Null),then perform Save operation,close the form after successful insertion and then reopen the form,then it retains the previous values during the form load......This is only in case where i leave a field blank in the previous data entry in the database.......But if i enter values in all fields then form load is working great.
How can I load a form and allow it to run it's code in the form load but keep it not visible. I want it to do what it needs to but but not display.
View 3 RepliesI have a VB app which draws primitive shapes (lines, filled rectangles etc.) into a picturebox control (from its paint event). I've since found out that a picturebox is probably the worst control to use for this. I've also found out that it's better to draw directly onto the form but I don't really want to do this as a control gives clipping for 'free'.
What would be the best control for this? The panel control looks like a good candidate but the experiment I tried actually performed worse

I have a borderless form that I'm "docking" onto the top edge of my screen. Inside of the form, I'm placing a single toolstrip control, which docks across the entire form -> (picture the taskbar to get an idea of what I'm talking about).Because the borderless form has no edge to it, I wanted to draw a black line along the bottom edg` of the form to differentiate the form from the windows or desktop behind it.
The problem that I'm facing is that`the toolstrip will not move "behind" the line when it's docked, no matter how I order the control layers.
I've tried programatically sending the control to back to no avail either.
Any ideas on how to get the line to show above the docked toolstrip?

View 3 RepliesI have made a custom control and the only change to the interface is that its a different color. Whenever the user moves their mouse over the control some white text fades in in the middle of the user control. Then after a few seconds the text fades out. The text is actually the location of the cursor but I have that figured out.
View 4 Replieshow do I draw over existing graphics drawn on the control. This is what I'm using to draw the objects:

Im looking for an image viewer that supports most types of image formats, including PDFs, and has the ability to rotate/zoom, and draw on an image. I've been looking but to no avail. Does anyone have any suggestions on the best way of going about modifying a control so that I would have these features? The main problem that I am running into is the lack of the ability to draw on an image. Im still sort of a newbie to .NET,

View 5 RepliesI'm looking to draw a trackbar normal, only with a transparent background. I have created a new class that supports transparent backgrounds set to true. Without using userpaint, the trackbar does nothing or takes the color of it's parent. When using userpaint I have to draw the control on mine own. Not quite sure where to start first though...
I've read about drawing a line (not so hard), drawing a floating object (to act as marker), and handling events on when the floating object moves left/right... Drawing 3 separate objects inside an inherited trackbar control seems like a clunky way of calling methods that should exist somewhere? Is there an easier way to draw the control normal without a background? If not, some in starting to implement all 3 new objects working together would be good (I could draw them separately but that's about it).
I'm trying to draw a 400x400 px image to a 400x400 form that I made. What I'm doing is:
Graphics.DrawImage Method (Image, 0, 0, 400, 400) 0, 0, 400, 400, ...
But when I run the form, the image seems to stretch slightly upon the y-axis, the x-axis seems to be working correctly.
This was what I was doing before (stretching the old smaller images to fit the size)
... (Image, 0, 0, 264, 231) 0, 0, 400, 400, ...
or something like that. Now that I'm trying to do it the correct way, I can't seem to get it to work properly.
Edit: I wonder if using a simpler verson of Graphics.DrawImage would work?
