I'm just trying to open a ColorDialog so that the user can select a color. But if I just use the following simple code with Button, ComboBox or anything, the application will completely freezes itself.
Dim cd As New ColorDialog()
If cd.ShowDialog() = DialogResult.OK Then
PictureBox1.BackColor = cd.Color
[Code].....
I'm trying to store the color (backcolor of a picturebox control) that the user has selected as a string as follows.
'mycolor as a string
If mycolor <> "" And mycolor <> "0" Then
Try
PictureBox1.BackColor = System.Drawing.ColorTranslator.FromOle(mycolor)
Catch ex As Exception

I'm getting some unexpected behavior with panel scrollbars, and was wondering if it is a bug, or simply something that I'm failing to do correctly. Basically, I have a panel with Autoscroll enabled. Then I put some other items inside the panel, and then make the panel smaller, so that the panel's scrollbars appear.
Outside of the panel I have 2 buttons, named "scrollOn" and "scrollOff", which turn the panel's scrollbar's on and off using the "Autoscroll" property (for example the "scrollOff" code I'm using is Panel1.AutoScroll = False ). So after I run the program, I move the panel's scrollbar down a little bit with the mouse (this part is necessary to reproduce the bug). I then click the "scrollOff" button (which should make the scrollbars disappear). But when I do that, the scrollbars are not only still visible, but they "freeze up" (can't move them with the mouse anymore).
I am at the form/application stage, and now working on my final project. I know how to open an application from the form, but I want to open the app within the form. I already have my web browser on one form, and button command that gets me there. I also want to run a special program that I have already created in the command window on the form that I have. I have the form ready, the command that I click to open the cmd.exe but, now it I cannot get it to run in the form, ie. a panel. At least that is where I think it should run.
my panel is called pnlcommandwindow, and I have it visible:false until I click the button. It opens with cmd.exe and command.com. But, I want the same window that is opened when I run a program in VB command window.
In the command button or the panel or another box?
I have an application that I want to review existing word documents. What I mean by review is that they can look at them and print them and that is about it. I am a bit stuck on how to complete this task though. I tried using a web browser and that allows changes and with a very minor bit of work the document can be modified and saved. I also tried using process.start and that just starts up the word application as does SetParent.
Is it possible to just take snapshots of the document and view those? Or to open the document as a readonly document?
i have a query of opening a new application or you can say a new Process in a Specific dimension means to say i have dropped a Panel in a WndowForm and i want to open that particular new process in that panel only.
View 4 Repliesnot quite sure why this is happening but I am just debugging right now and the buttons I am using are opening the wrong forms, I have made sure of the form names, button names etc and it looks all good but specifically the btnPrintReport is opening up the form enterAuditForm while btnProcessAudit is opening printAuditForm instead of their correct ones.
Here's my code, it is rather simple. The reason why I am using a separate sub as my btnPrintReport is because I am using that also on the baseForm's OnLoad Event, which again is also opening the wrong form.

View 2 Repliesi am not able to figure out any code on how to do this. I am trying to make it so when the person chooses a color in the ColorDialog, the all my buttons forecolors go to that, then the dialog will show to pick a back color.
View 2 RepliesA user places the cursor in a table cell and clicks on "Table > Background Color" to edit the current background colour.Currently I have been able to detect the current colour (for instance a light blue) and set that colour in the ColorDialog (Colour swatches are correct and RGB values are correct).What I would like to do is enable the user to click on the "Add to Custom Colors" to save the colour. Problem is, it sets the first square in the custom colours area (which happens to already be filled in with another custom colour), rather than finding the next square that is white and set it there instead.

This is how i am doing it currently, but for some reason the customcolors are not being added. i know for a fact that my array is good because i checked it.

If you are working on a project that requires non-standard colours for text, it is possible to choose your colour by specifying the RGB components in the boxes on the colorpicker or by moving the mouse around until the desired colour is obtained. This can be put into one of the custom colour boxes and used until the program is shut down. Is it possible to save that colour to the custom colour box so that the next time the project is run, the chosen non-standard colour re-appears in the custom colour box?

View 1 RepliesI 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.
