I'm using the following method to move a picture box that is in a 24, 24 panel:[code]This is obviously the worst way of doing this. But, it's the first thing I could think of and Googling has brought me no luck so far.

The following code works perfectly to allow moving a control on a form at run-time. However, when AutoScroll is set to True on Form1, and you drag Button1 past the right and/or bottom bounds of the form, it goes haywire. I really need someway to smoothing control the autoscroll so that as you scroll the control off the form, the scrollbars smoothly appear.

I have a panel that has 9 pictures boxes within it. I need the User to be able to create as many instances of this control as they like.
Then each control needs to be able to move freely within the form.
I've created the control and added the appropriate code to move it around the control.
I've made the control canvas the same size of the panel. The problem is that when I move the panel, it only moves within the bounds of the control canvas. I guess I could increase the size of the canvas, but then additional controls would still only be able to move within their bounds and it would come out all wrong.
Is there anything I could do about this? Or is there a better method?
How to move a label up, down, left, right inside the panel control? The label should move up when I press a "button for up", the label should move down when I press button "button for down".
View 9 RepliesI have asp.net chart intervel issue. I am feed data to chart like below
X1 Y1 X2 Y2
100 907 500 2395
100 745 500 2343
100 760 500 2403
Each row is a series in the chart.
In am iterating each row in code and making new serie and adding to chart
series1.Points.AddXY(dt.Rows(i)(0).ToString, dt.Rows(i)(1).ToString)
series1.Points.AddXY(dt.Rows(i)(2).ToString, dt.Rows(i)(3).ToString)
Chart is coming like it is fine. Now I want make interval like 100,200,300,400, 500 (500 is max of the graph). I tried Chart1.ChartAreas(0).AxisX.Interval = 100, It did not worked out.
I am trying to get AxisX interval for MS Chart Control in code behind. But when i try to retrieve the value, it returns zero even though it has a default value.
'Doesn't return the correct value, only returns 0
Dim XInterval As Double = mainChart.ChartAreas(0).AxisX.Interval

I have dragged and droped a timer control "tmrGetMappingXML" from the Common Controls Tab in Tool Box. The issue that I am mentioning also appears for the Timer Control present in the Components Tab in tool box.
In the form Load I have written:
HTML
tmrGetMappingXML.Interval = 3600 '1 Hour = 3600 Seconds
tmrGetMappingXML.Enabled = True
tmrGetMappingXML.Start()
The timer interval is also set in the design time to 3600 seconds. But the Tick event of the timer fires continuously every second.
If I have a very large function/sub in a class that is an instance method (i.e., not Shared), do I gain or lose anything by moving that to a shared method and then declaring a small stub method for the instance use?
I.e., I go from this:
Public Sub MyBigMethod(ByVal Foobar As String)
If String.IsNullOrWhitespace(Foobar) Then
Throw New ArgumentNullException("Foobar")
End If
[Code] .....
My thinking is I save on memory size per each instance of the object. Because each instance only has to lug around the stub method which handles calling the shared version and passing an instance of itself to the shared method so that it can do whatever it needs to do. But I'll wager that I sacrifice a very teensy amount of speed because of the added function call overhead.
I found a custom ListBox that, strangely doesn't have an InsertAt method and I would like to add one. The custom ListBox uses an object instead of just a list of strings like a normal ListBox. I was curious what the logic behind inserting a new item at a particular index would be.The only thing I could come up with was add the new ListBoxItem at the end, then using the specified index, I could either keep moving ListBoxItem objects to the bottom, with the Add() method, from that index till the ListBoxItem at that index equals the one added, or I could use that index number in a "calculation" till I know I've moved the correct number of objects.
View 14 RepliesI've completed projects similar to this in the past but this one has me stumped. Trying to retrieve text from a text box in a third party application. Using SPY++ I found that this control is the second control in the list so I coded the following: Dim parentWindow as integer = windows.ReturnWindowHandle({windowname})
If parentWindow > 0 then
Dim childWindow as integer = FindWindowEx(parentWindow, 0, Nothing, {child window name})
Dim field as integer = 0
[Code].....
This worked great. Closed the app, came back the next day and this same code did not work. Used spy++ and found that the control had moved to the 4th position. Closed it, reopened it, this time it moved to the first. What is the best way to find this control each time when there are are 50+ controls on the screen and they all appear in spy++ like this:
Window 0022063A "" Edit
Window 00270652 "" Edit
Window 001A0630 "" Edit
and they continue to rearrange themselves each time the application is closed and reopened?
Is it possible to dynamically direct a particular control's event to use a predefined method. For example: I have a form which I dynamically add controls to, let's say, TextBox1, TextBox2 and extBox3 and a module which as 3 routines, Method1, Method2, Method3. When I dynamically add my controls, eg TextBox4, I want to choose which of the 3 methods I want mapped to which event.
I was thinking of something like this...
Dim objTextBox1 as new TextBox
dim NameOfRoutine$="Module.Method2"
Form.Controls.Add(objTextBox1)
Call AssignMethodToEvent(objTextBox1.GotFocus, NameOfRoutine$)

View 8 RepliesI have an MDI form, and all of its children have a timer control. I also have an options form where the user can change the automatic refresh interval, which is loaded from the parent. The interval is stored in My.Settings.UpdateInterval as a Double.What is the best way to update all of the timer interval of the Children? Can the Children listen for an event in the parent form (UpdateIntervalChanged)?

Is there an option to set a time interval between each check? Because it will load the page (it's not google, it's my personal website with some information needed) and it need to be fully loaded till it gets the information then it would do another check for another listbox1 item.

View 12 RepliesI have been making an online role playing-game in VB2008 and inside the gameloop for the client there is some code that "smoothes" out the movement (instead of it being choppy from tile to tile.) It works pretty well but I'm having problems figuring out a math formula to get a good frame timer interval to set how fast the frames change based on how many pixels they can move per loop.Testing stuff out I found that 250ms is an ideal frame timer interval for 1.0 pixel movement per loop. If I were to double the movement step of pixels by 2 lets say (2.0 pixel step per loop) I found that the frame timer interval should be around 125ms. How can I get the frame timer interval by the movement step of pixels? In cases where the movement step can anything between 0.1 to 4.0 pixels.
View 3 RepliesI need to determine which tab the user is coming from, and going to, when they switch tabs, and possibly cancel the switch. I have tried the Deselecting, Deselected, Selecting, Selected events, and all of them show the e.TabPageIndex to be the same as the sender.SelectedIndex.
Is there an event, or property, that I can use so that I can determine both sides of this, or do I have to hack something together with caching it from one event and using that value in the new event.
I am trying to avoid handling the Deselecting/Deselected events and caching the value to use in the Selecting event. I already know I can do this, so I am asking if there is a cleaner way, without doing this.
I have tried in both C# and VB, with the same results (no surprise).
I am just wondering how you can move a control toward the another control in VB.net. I have searched everywhere and cannot find a solution.

I have a datagrid control on my form that receives data from a device on the COM port. I strip out the data I need and put it into the currently selected cell. When I load the grid, I find the first empty cell and set the focus so each load presents the user with an empty cell to start receiving data. Once I get the measurement, I need to move to the next cell down (like hitting enter in the grid). This will allow the user to do measurements with the external device without having to move to the next cell.
