Saving Window Size And Position Multiple Monitors Toolbar Position Etc.

Aug 24, 2009

I have looking for a tutorial or class that demonstrates more than a trivial example of saving a windows position on closing. The ones I have found don't seem to work on all systems because of:

1. Multiple monitors. (and resolution between those monitors)

2. Toolbar size and position (toolbar is only on the primary monitor, well sometimes)

3. Sometimes the programs dont open on the right monitor they were closed on.

Is there an extensive class or tutorial on all the stuff a programmer needs to get right to have a window size and position persisted between executions?

VS 2008 No Row At Position 0?

Jan 24, 2011

i've been creating a program in VB that connects to a Microsoft database, and up until now, the program has been displaying the information fine. however, all i get now is the error message "No row at position 0" whenever it tries to display almost anything.

I am baffled as i have 3 forms that work and are programmed exactly the same way and only 1 works fine :/

VS 2008 Position On A Row In DataGridView?

Jan 3, 2011

in my form, I have a DataGridView and TreeView apart from other controls. Now, the data shown in the DataGridView is also displayed in the TreeView. What I need doing is that when a node in the TreeView is selected, the corresponding row in the DataGridView needs getting selected for further action.I used some logic to determine the DataGridView row. But, I am unable to select the row. When I use the DataGridView.Row(index).Selected function, the row is selected, however, the row index does not change.

VS 2008 : Getting The Position Of A Child Control?

Jan 22, 2011

In your opinion what API use Spy++ to get the "Rectangle" and "Restored Rect" data of a child control of an external window?I don't think it uses GetWindowPlacement because if I use this API for the main window I obtain the same values of Spy++, but if I use the GetWindowPlacement API to find the position of a control of the window itself, known it Hwnd, I obtain different results as to Spy++ (that are ALWAYS the same results also if I shift the Main window... so I think that are relative data and not absolute data... but they are wrong )

One example:
Spy++ : (620, 473)-(792, 505)
GetWindowPlacement: (615, 450)-(787, 482)
same dimensions... but different pos... and the right pos is the Spy++ pos.

VS 2008 Starting Position Of Form?

Jul 7, 2011

I have a "Please Wait..." form that I show when doing some long task. This works quite well. But I cannot seem to control the opening position of the form. Currently I am using:

WaitWindow.StartPosition = FormStartPosition.CenterParent
WaitWindow.Show()

and this is just being ignored. The window opens at random locations. If I change it to CenterScreen, that works! But I don't want it center screen, I want it centered on the parent. Can I manually set the location? I am using VB 2008 Express and the wait form is a plain windows form.

VS 2008 Webbrowser Scroll Position?

Jan 6, 2010

What I am doing is I have an image in the webbrowser control that I am trying to capture and save to my computer but the image url is created dynamically and destroyed on the loading of the page (which keeps me from being able to use httpwebrequest to retrieve the image that corresponds to the page I am currently on). To get around this I am resizing my webbrowser control to the size of the image and taking a snapshot of the browser window itself.

The problem isn't with taking the snapshot... it's that when I take the snapshot it is snapping an image of the browser window prior to scrolling. I would like to figure out the scroll coordinates so I can basically write a function that will "pause" the routine and wait until the scrolling coordinates match that of where the image is located and then proceed to take the snapshot.

I have tried the .ScrollTop / .ScrollLeft values and .ScrollRectangle.Location.X/Y but I keep getting 0 as a return. Does anyone have any information on this? I've searched all over google but only find people asking the same question as me but recieving no answer.

Get Closest Position To Specific Position?

Mar 9, 2010

I also have a function that returns ALL tiles on the map and they're X, Y position. How could I find out which one is closest to the position I specify? I can't figure out how to go about it. how to implement it with this. Heres a MADE UP example if what I'm trying to do:

Dim MyPosition as New Position()
MyPosition.X = 400
MyPosition.Y = 400
Dim tList as New List(Of Tile) = MyMap.GetTiles

Now, I can already do the stuff above, but what I need to make is something like this:

VS 2008 - BindingSource Position Changed Event

May 5, 2009

I datagridview and I populate it using a bindingsource. I have the following code in the bindingsources PositionChanged event and it works as I want it to except when I filter the bindingsource.

Private Sub ProductBindingSource_PositionChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ProductBindingSource.PositionChanged
If (Me.ProductBindingSource.Current IsNot Nothing) Then
Dim dr As DataRow = CType(Me.ProductBindingSource.Current, DataRowView).Row
Dim ProductId As Long = CLng(dr.Item(2).ToString)
Dim ResultId As Integer = CInt(dr.Item(0).ToString)
GetReport2(ProductId, ResultId)
End If
End Sub

The scenario is when I click on a row in my datagridview the bindingsources positionchanged event fires and I load a crystal report. Problem is when I filter the bindingsource, even though the first item in the grid is now different the incorrect report is displayed because the bindingsources position hasn't changed.

VS 2008 Inserting A String Of Text At A Certain Position?

Sep 8, 2009

far it works! But it work's too well. What I'm trying to do is insert a string of text at a certain index position of a text file, underneath a certain line of text. So far I have:

'Controls Var 16
If CheckBox1.Checked = True Then
If Mytempstring.Contains("zrandomtextz=0") = True Then
Mytempstring = Mytempstring.Replace("zrandomtextz=0", "zrandomtextz=1")
ElseIf Mytempstring.Contains("zrandomtextz=") = False Then

[Code]...

It's inserting the text, but it's inserting it at every line of text in the file. So instead of one instance of "zrandomtextz" underneath "xinserttextx" I get "zrandomtextz" before every single line in the file. Can someone please help me as this has been an issue for months now? Edit: There are quite a few lines above this one, as in 50-150, so I removed all of the above section, however I can assure you that whenever it is simply replacing then writing to file it works flawlessly, it's only now that I'm having problems and this is when I try to insert new stuff under stuff.
