VS 2008 Getting A Dot To Draw Based Upon X Y Coordinate On Form Load
Nov 16, 2010
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.

Dear all, I'm new in the forum. I have a simple but annoying problem: 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 loa
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Graphic As System.Drawing.Graphics

I am trying to convert a vb6 program based off of the coordinate system. VB.net does not seem to recognize any of it.

I am reading the memory from a game and I have managed to find the x,y,z values of the player (z is irrelevant). Now I am trying to make some sort of a waypoint system and I thought it would be best to make a small coordinate based map that will act as a birds-eye view of whats going on ingame. But I don't know where to begin creating this thing, since it needs tons of xyz values.Just throwing this in here since I've already made the thread:I also want a small circle to represent the player that will turn, facing waypoint 1 and move in a straight line towards it.

These are my variables:
PlayerFacingAngle, PlayerPositionX, PlayerPositionY, PlayerVelocityX and PlayerVelocityY

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 set my FormBorderStyle of my form to none.This is exactly what i want, except I ran into a problem.When the background is gray (background of other applications running in the background), my form tends to fade in with the background (Still active, but i cant see where my form starts or ends).

does anyone know how to connect points of a label? Let's say I have a label and start the label at point 0,0. Aterwards, the points jumps to 3,6 ... then to 6, 9 dynamically based on incrementing 3. How do I show for example, the path it takes to let users know where they are? for example, 0,0 --> 0,3 --> 3,6 --> 6,9 --> etc. I've tried with drawline but unfortunately, this leaves my lable in a mess.

The 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.

below i have the form which i made in access, its BIG, REALLY BIGI am going to try and recreate this form using VB and MySQL, the question is how?The purpose of this form is to display all locations ready for someone to enter in information into them, normally the first field in each table has a unique name (which is set as the default value for that field), in the morning, the only field which is altered is a sign on field, which in access, the user clicks and the time is entered.

i am having an issue populating two combo boxes on form load. The program will connect to an access database and pull data as instructed. Then as it pulls each record it puts it into the combo box.
This was working.. atleast i think it was. i dont recall it ever not working, however i wasn't looking for it.
My problem is that if when i load the MDI parent form and have it skip the selection form and the login form and load the next form in the sequence, it loads everything perfectly. However if the select form is loaded first, then the login form and then the form i need loaded, it will not populate. The only difference between the two different loads is that the login form calls a function that loads the form as a new project.form
I did this so that I can have multiple forms open at a time. I am assuming my problem is that I need to get the child forms handle then populating controls using that handle? but i think if I had to do that then I would beable to populate the comboboxes on the first form load using the login method of opening the form.
Here's my code.
vb.net
Private Sub frmLine1t5_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.Text = "Line " & LineNumber & " Test Form"

I have a picture box on a form that changes size as needed. Both by resizing the form and by code.How can I resize the form automatically if I resize the picturebox in code. The client area of the picture box should not be clipped.Right now the picture box is set to dock fill, but if the code resizes it, the form does not follow it. Is there a binding somewhere I can use?

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.

I am trying to get the green label box to show the correct coordinate after the box is scaled. The red box always shows the true coordinate of the mouse in the picturebox. So for example - after you click on [Scale x4], the 32x32 picturebox will be 128x128. The red box will now show from 0-127 x and y. I would like the green box to show 0-3 x and 0-3 y. Does anyone know how to do this? The code is ready to run, just cut and paste. [code]

Basically I want to move my mouse to the coords that is received based on the location of a certain coloured pixel. I can get the coords of the pixel but when using them on mouse position, the mouse position is based on the entire screen rather than the form. How could I change the position coords based on the form rather than the entire screen. E.G. If a certain coloured pixel is 2,2 in a form and I put that as the mouse position, it would go outside the form but I dont want that. I want it to hover of the pixel coords
This is my
Dim bmp As Bitmap = DirectCast(PictureBox1.Image, Bitmap)
For x As Integer = 0 To bmp.Width - 1
For y As Integer = 0 To bmp.Height - 1
If bmp.GetPixel(x, y) = (Color.FromArgb(108, 90, 60)) Then
Windows.Forms.Cursor.Position =
End If
Next
Next

I was trying to resolve the issue with my form not loading to the following an just gave up cause its been a cat an mouse game as I stated in the last thread.My project is having difficulties with a code. For some reason it's not letting frm FakePM. Show open the form.Ive used this over an over time an time again, its just not doing it now. The following code opens my Fake Pm part of my program: [code] An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object.Now Ive used frmfakePm or frmAbout or frmOptions for other form applications an its never given me this kind of error.It gives me a error on my FrmFakePm form of my Private Answer Strings, The Dim code is in green, the Private Answer Strings are in yellow.
