When another window, I have been using Calculator, is in front of my app, and it is moved around, it leaves ghost images until I get the picturebox refreshed. I assume that it has to do with the number of items that I am drawing, which can get extremely high. Here is PictureBox1.Paint handler.

How to set picturebox a front of textbox? I get always this: [URL] I wish like this: [URL]
View 7 RepliesI used a picturebox to allow user draw lines by mouse. I used this code in mouse down:
Dim D As New System.Drawing.Pen(DrawingColor, 2)
Dim g As Graphics = PB.CreateGraphics()
g.DrawLine(D, X1, Y1, X2, Y2)
but when a window appear on front of picturebox... its seams that picturebox redraw itself, so drawn lines erased.
I have an application of which only 1 instance can run at the same time. Thus in the StartUp event I check for this to be true, and if not close the new instance started. At the same time though I'd like the application to switch automatically to the instance already running. By finding the processid of that instance and using appactivate this is working properly, except when the instance already running is minimized. It then switches to it, but since the instance is minimized, its ide will not show.
I need to use something like sendmessage, but am not able to find how.
-Since I already have the processid, could someone tell me how to use code to maximize and bring to the front the ide of another currenly minimized application?
I want to do a check to see if a item is in front if not then do MyItem.BringToFront else MyItem.SendToBack
View 1 RepliesI've been working on a way to check a user's hardware for performance reasons and have been using WMI to find almost all the information I need. One thing absent is the FSB of the processor (it's not in the Win32_Processor Class as far as I can tell).
Does anyone know of a way I could go about to find this using an API, Memcopy or something?
How do I make it so that when a user brings an explorer folder on top of my app - so that they can drag and drop a file into a grid control
[edit] - it's actually a listview that they drag into - but that shouldn't matter [/edit]
That when they drop the file my app fires off a AddFile.ShowDialog pop-up form
I want that AddFile form to be in front of the explorer window

I have a PaintEventHandler connected to a picturebox via AddHandler.
In PaintEventHandler I have coded this for writing the drawing to PictureBox1.Image:
Dim PictureBox1 As PictureBox = CType(sender, PictureBox)
PictureBox1.Image = New Bitmap(PictureBox1.Width, PictureBox1.Height)
Dim bmp As Image = PictureBox1.Image
Dim g As Graphics = Graphics.FromImage(bmp)
... drawing something ...
PictureBox1.Image = bmp
Everything works fine but after running through the paint event handler and showing the picture on the screen it calls the painthandler again and again. It does not stop.
Replacing the code above with
Dim g As Graphics = e.Graphics
Makes it running. But then I cant save the Image to a file.
I would like to know if its possible to show up a form in front of all other opened apps . Exemple : myapp.exe (is under of all those application) internet explorer , photoshop , windows live messenger. On event (for exemple on new message recived) myapp.exe will show up all over other forms.

I am working on an excel add-in. Currently I have a couple of forms that grabs info from excel, processes and pastes data back into excel.My problem occurs after my form closes (this leaves excel and one other MDI form still open). I need my excel sheet to come to the front for users to view and edit. My MDI form just stays on top even though I just edited the excel doc. I have tried everything I can think of using:

View 6 RepliesI use a program called Taskix that allows me to grab a button on a taskbar (for programs that are active) and drag it to reorder them. So the functionality exists somewhere, but most obviously through some sort of API.
What I want to do is allow my users to choose if they want a particular window in my program to sort itself to the beginning or end of the taskbar list. I know I want it because I would prefer this particular window to be in front of my opened windows whenever I make it visible.
where I might be able to access an API function that accomplishes this? Finding something like this on Google has proven to be fruitless; for me at least.
In one of our application the parameters passed to a stored procedure in this way
Dim parm As New SqlParameter("searchText", SqlDbType.VarChar)
parm.Direction = ParameterDirection.Input
parm.Size = 50
parm.Value="test"
cmd.Parameters.Add(parm)
and the procedure contains a parameter as @searchText
ie the parameter name passed from the code is searchText and that in the stored procedure is @searchText .
But it is working properly, i am always getting the required results.
So my question is like so there is no need to specify @ before the parameter? Whether it will append @

View 2 Repliesclick on a picturebox and get a 'mark' to appear. (This currently works just fine using the code below.)I would like to have only one mark on the picture box at a time, i.e., I need to remove the previous mark on each mousedown event and I am unsure of how to get this done.Once the user has placed the mark correctly on the picturebox they will fill out a few extraneous textboxes of information and press a 'save' button. This will update a table (currently access) with that extraneous data plus the x and y of the mouse position when it was clicked.What I would like to do at this point in the process is remove the mark from the picture box and in it's place add a premade 'pin'. Sort of the thing you do in google earth. This would be a jpg or bmp or png file. The type does not matter.

View 2 RepliesBasically, I have an Access database with Primary keys that are structured with this format ("02"000).When I try to paste the number, it ignores the "02" and goes straight to 000.For example, here is the code;
PeriodRoomID.Name = ("R" & ds.Tables("sqlSpecRoomRequest").Rows(i).Item(1))
What PeriodRoomID.Name should be is R02001.What PeriodRoomID.Name comes up as is R1.It ignores the "02" and ignores the 0s. This makes sense mathematically but it is not what I want. I need a way to get the exact output and not some simplified version.
The query;
SELECT SpecialSoftware.SpecSoftID, SpecialSoftware.RoomID, SpecialSoftwareNames.Description, Rooms.Capacity
FROM SpecialSoftware, SpecialSoftwareNames, Rooms
I have a value that shows a integer value between 0-100. For a little math, I need to be able to add a decimal in front of the value. So if the value was 50%, I need it really to be .50%.

I've selected two rows of data from one of the tables in my database and pivoted it, making two columns. What I would like to do is add a column in front of the two, and use that like a rowheader, I'm unable to use the actual rowheaders at the moment because I'm exporting the datagridview to word and I'm unsure how to get the rowheaders in, so I thought to just add in another column for the time being.
So, how am I able to add in a new column in front of the others? Or even better, how can I include rowheaders when I export a datagridview?
