way to stop resizing a panel here's what i got:
I have a CaptionPanel containing a DataGrid. The user is not allowed to resize the panel beyond specified values (min/max height and width).
In the resize funtion (handling the resize event), i'm putting conditions on the height and width:
Private Sub myPanel_Resize(ByVal sender As Object, ByVal e As System.EventArgs) Handles myPanel.Resize
if myPanel.height>maxHeight

I used to use the following instructions to lock my form from stretching.
Me.MaximumSize = New Size(550, 550)
Me.MinimumSize = New Size(550, 550)
Then I needed to keep the Form size fixed so I used:
Me.ClientSize = New Size(625, 500)
This makes it stretchable.How can I lock the Form from re-sizing?
I've been programming a Fisheye-panel that holds image and make it behave like the icondock in Mac Os X. But now i have a problem. When i add to many item, i want them to shirk, to make room for more, or grow when i remove icons. This is the behavior i get: When i want them to grow, they don't grow at all. When i want them to shrink, they shrink, but leaves lots of empty space (like replacing a photo from a frame with a smaller photo. The image shrink, but not the frame)

View 3 RepliesWe have two update panels on our webpage. Now first update panel is having button cancel. While second update panel is having a file upload control.Now if the user uploads a file that is going to upload in about 2 mins, and in between, say after 30 seconds the user clicks the cancel button, the upload taking place in update panel 2 should stop.
View 2 RepliesI have set a scrollable control's autoscroll to true. What do you do when you don't want a scroll to occur? For example, suppose you have a RichTextBox and a button side by side as below:
Notice that "button1" has the focus. If you click on the RichTextBox to give it focus, the scroll bars will scroll until the upper left corner of the RichTextBox is in view.
But what if, for whatever reason, you wanted to keep button1 in view? How would you do that?
I need to center the red panel in the middle of the dark grey panel, when you resize the form the red panel should be in the middle, and the red panel can't be resize, anyone have a code or property to do this?
View 2 RepliesAlright, so I'm still working on the slot machine. I have three timers all independently going for my three "wheels" of the slot machine.
My issue, is that I'm trying to make a Stop button to stop each timer one at a time, and I'm not understanding why this code isn't working. The logic completely makes sense, and the first "wheel" stops when I click the button, however, it doesnt appear to stop the other two timers.

I would like to add an effect where a panel sweeps out of the way to make room for another panel. This is sort of like a sliding effect, and I think at one point in time this could be seen on Apple's website under their product pages. I came up with some code, but it isn't working.

When a user is editing a given piece of data, they're allowed to add messages/comments. These are stored as child records in a SQL database. Clicking on the Add Message button brings up a panel (pnlMessage) courtesy of the AJAX ModalPopup Extender. This takes some input and, when the "Send Message" button in the panel is clicked (I learned the hard way to NOT make that the 'OkButton' property), the message is stored in the database and an email is sent to the intended recipients. No problem there.
However, I need to be able to allow the user to add new email addresses (so long as they are registered in our database). I have another ModalPopup / panel combo (pnlSearch) that's tied to a button on the previous panel (pnlMessage).
The user is supposed to be able to add an email or click on a search button to populate a list to choose from.
The pop-up panel (pnlSearch) comes up just fine, but clicking the "Lookup" button (which instigates the search and returns a collection of records that the user is supposed to pick from) closes the panel.
Previously, I ran into the problem of having the Button.Click event never firing when I put the Button into the "OkControlID" property (the CancelControlID works fine since I don't want to do anything). Removing the "OkControlID=Button" line allowed it to work perfectly with the Button.Click event firing as expected.
So now I have the Search panel with a button for "OK" and a button for "Search" - but the panel should stay up and visible after the Search.Click does it's thing. Am I missing some property that basically says "don't close the panel when this button is clicked"? Of course, if I bring up the panel again in the same session, the results from the previous effort are there (the search results).
I have a TopBar, A LeftBar, A VScrollBar, A HScrollBar and a Panel inside a SplitContainer Panel.The issue I'm having is that when my SplitContainer Panel is small enough to enable one of the ScrollBars, I will slide the ScrollBar and then when I resize the Split Panel, my Panel1 is staying where I scrolled it too.I'm having troubles thinking of the correct code to fix this.

I created a form and have the variable inputs for 4 motor run statements. Then with a start button the script starts and it is surrounded by a for next statement to loop 10 times. It works fine but if i need to stop the execution of the script with a stop button. I put the stop in a new section but of course does not work to do a motor stop. It just causes the exe to not respond till the loop is complete. Just need to be able to stop the Run1_Click button section.
Edit:I do not mind if it finishes the 4 motor run commands and then stops execution of the loop. So need to figure out a way to trigger a stop from a button on the form to stop the cycle. For the future the loop will be a variable integer input so 10 will not be the standard.
Edit::Does a ' Do ' statement sound like the thing to use? If so how and where would I place that? Have a Stop button on the form and it would stop after the 4th motor run command.

This is for a mapping/plotting program.
t.panel is the main panel and it has too much content to fit in one screen so there are scroll bars. x.panel contains the horizontal scale for the data points in t.panel. I drew the scale using a bitmap and set it as x.panel's background.
Setting x.panel's horizontalscroll.value = t.panel's horizontalscroll.maximum doesn't seem to work. I think this is because x.panel's doesn't have any content that causes it to need scroll bars.
I have a START and STOP button and when the user clicks "start" the program does a whole bunch of calculations and all. However, I noticed that when I was testing the program I clicked STOP the program continues to execute stuff.
My START code is basically a while loop that iteratively does some calculations.
So I just put a boolean variable as the while condition and when user clicks stop its set to false and when user clicks start its set to true. However, when I click stop, the condition is set to false yes but it still executes all the code until the condition is re-evaluated right...so my question is how can I get out of the while loop when user instantly clicks "stop"?
I have a problem with a certain panel in another panel.
I have declared a panel on my mainform that is called panel1 ( dock: fill)
In this panel is another panel ( panelmain )with size 10.000, 10.000 pixels. Now I put the auto scroll property of panel1 to true, so then the panel1 has scrollbars on both sides and can show the whole panelmain.
Now the user has the ability to zoom, which basically means that I just scale Panelmain with all it's child controls.
Like Panelmain.Scale(0.95) ( To zoom out )
And panelmain.scale( 1.05) ( To zoom in)
This works well, but when the user is using the scrollbars in panel1 and after that zooms in ( or out ) the location of panelmain is changing. So I tried to solve this by docking panelmain inside panel1 at the left. But now the vertical scrollbar is gone. how I should dock panalemain inside panel1 to prevent panelmain from moving around but also in a way that both the horizontal as the vertical scrollbar are present?

I have 2 panels on the form butttt for panel one i want to slide height and panel 2 i want it to slide width.
In VB6 I could embed a panel or picturebox containing controls or images within an outer panel or picturebox. If I moved the outer control then the embedded panel would move with the outer panel and stay in the same relative position, which is what I require. This doesn't seem to happen in VB.NET, the internal panel stays fixed in its location, even if I have pasted this panel within the outer container. Is there are trick to this or do I have to code to get the internal panel to move with the outer one? How does an internal container remain embedded within an outer one?

I didn't really think about it at all while I was making the program.
View 1 RepliesHow to make my forms resize automatically. here's the situation. I have my intro screen, which a user may want to maximise. Once this is maximised, the whole program should stay maximised. Again, if the user chooses to restore the window to its default size, the whole program should remain in that default size. However, once the user clicks the button "Press here to start" on the intro screen, the form automatically reverts to its original size if it was maximised. I also need to be able to stretch the contents in the correct ratios to fit the new screen size.
