How would I be able, with the click of a button, allow the user to draw on the form? Maybe as if, taking a screen shot of the whole form, and then drawing on top of it? Dose not have to be a lot of colors, just a simple way to draw a line.

I am writing a program wherein the user draws shapes by clicking a button for the desired shape and then clicking on points on the drawing area. I cannot figure out how to store four clicked points to create a foursided polygon. I read many articles that say use the "mousedown" command and store points in a list, I have tried but it's not working for me. To summarize, I need the user to click the polygon button, go to the drawing area, click four points and have a foursided polygon created.

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 each of my form I have put an 'Exit' button. When user clicks it, another form is displayed (I don't want to use 'MessageBox') asking user whether he really wants to quit. If user clicks yes the form closes. If user clicks no, form is redisplayed.
However, out of 4 forms only one form refuses to redisplay. The code is exactly same on all forms. I have included 2 Express 2008 projects showing one form each in the zip file apps-ssk.zip

I have an MDI application. Upon starting it, the MDI form is instantiated, then it kicks off a Username/Password log-in form and makes itself invisible(user never sees the MDI form). If the user logs in, the log-in form becomes invisible and the MDI form becomes visible. This works fine, except for one user.When the log-in form comes up, the MDI form is also visible. If he clicks on something, it crashes(certain variables aren't set at that point). If he logs in, however, the log-in goes invisble and everything works fine. This guy is a network admin/IS type and has several versions/hotfixes of the .Net Framework installed. Could that be the problem? Does anyone know what could be causing this problem for this one user and no one else?
View 2 Repliesi am trying to log a user in using a login form. i have my connection to my database and there and it connects just fine but it will only read the first row. here is my code.

I have a Mdi form and I need to put a control on the form which the user can resize. Now I need a container can be dragged by user to increase it's size. The split container will not work in my case as I have childforms and stuff. I want a container whose size can be increased by dragging it on one side.

View 2 RepliesOk, so i am trying o make it so that a user can change themes, i have moved all major code to a module so it can be accessed but then i have a problem.
I have 6 forms, all forms are the same just different themes, The problem is that in the module it calls form1, like for example form1.webbrowser.blah.blah, if i user used form3 for there theme then this dones not work as in the module it calls form1.
Basically i need to add something else there like for example:
dim Cform as string
Cform = form1
Cform.webbrowser.blah.blah
But form1 can not be a string
im trying to make it so the user not able to resize my form. i cant figure this out
View 1 RepliesI am jsut adding bits on to a Windows Service we are making here at our company, its an Asset Management tools with a few built in extras. It runs as a service on everyones machines but we can also do things like request a reboot etc through it.At the moment when We send a Reboot/shutdown etc command to it the Service on the machines calls 'C:WindowsSystem32Shutdown.exe' with the appropiate switches. This displays the windows shutdown warning to the users but nothing they can do about it.
What I was wondering if I create a seperate exe (or even better built into the service but I am not sure if this is possible) instead of the Service Calling 'shutdown.exe' it calls this form up to the user which states that we have requested a reboot etc but there is a 'Cancel' option. The Cancel can just end the form/program and nothing more, if the timeout that we specify is reached then that form/program then calls shutdown exe for an instant shutdown.
I know that the Service runs in a different user Space and we have no telling of who is logged on to that machine so I will need a way to just launch the form to any logged on users. Doesn't matter to much if there is no one logged onto the machine but if it does display this form while noone is logged on that is not a big deal.
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?

But I cannot check out where on the screen the click was done and so I want to draw two short crossing lines on that point as marker where Visual Basic clicked on screen. If it is possible to move cursor to that position and show it then it is as good as drawing marker.

On 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.
