Removing Tabs With User Control From Tabpage
Nov 19, 2009I have a application with a tabcontrol. I dynamically open new tabs on which there is a custom control which is made of a graph and a datagridview with data. I fill this from a csv file. when I open few tabs like this my application memory goes over 120 MB. When I remove the tab I call the dispose on the custom control and a dispose for the tab. But the memory stays where it was (120+MB). It goes down only if I minimize the program. And when I show it again its around 10MB.
View 3 Replies.Net Form Activate/Deactivate Event Firing Issue After Removing A TabPage From TabControl?
Nov 28, 2011I've recently run into an unexplainable issue regarding a windows form application I am working on. I've managed to isolate the issue to a single line of code whereby a single TabPage is removed from a TabControl, leaving no tabs left in the TabControl's collection. What happens next is a bit mystifying: my application proceeds to enter a state in which the main form's Activate event is fired subsequently followed by its Deactivate event. As a result, no matter where I click on the form, the application will activate for a split-second then immediately deactivate itself, thereby causing me to be unable to interact with any other GUI controls on the form. I thought maybe another thread is trying to interact with the deleted tab object, but the tab is created and destroyed on the same main gui thread. Does anyone have any insight that may point me in at least a new direction? Stepping through the debugger to the point in code where the tab is removed does not cause any exception to get thrown, so at first glance there doesn't appear to be any coding issues going on (although I would not be surprised that is actually the case!).

Using System.Windows.Forms.TabPage To Store An Entire TabPage For Later Use?
Jan 8, 2009I am using System.Windows.Forms.TabPage to store an entire TabPage for later use in My.Settings. Here is a brief description of the application.
I have a TabControl that has 3 tabs. One for user input, another tab for equipment settings, and then a final tab for Oven settings. On the user input tab, if the user de-selects the checkbox for Oven, the oven tab is saved to My.Settings and hidden.
I can then run the application without oven control. After running, lets say the user would like to re-run, this time with the oven. They go back to the input tab and re-select the Oven checkbox. However, the Oven tab doesn't re-appear. When stepping through the code, the is nothing stored in My.Settings for the oven tab page. Why not?
Also, I can open the application, and check, then uncheck the oven checkbox and the tab is hidden, then returns. I can do this all day. However, after running the tab will not return.

Removing Specific Lines Of A Multiline Textbox
Feb 26, 2010What I am trying to do is remove lines of a multiline TextBox based on certain criteria, such as the number of characters or words. For example, if I paste a list of phrases into the TextBox, I want to remove all phrases that contain more than 25 characters. Once the phrases are removed, I then want to remove the empty lines that are left behind, but I have commented out the ".Replace(vbCrLf & vbCrLf, vbCrLf)" for the sake of making the results easier to follow (see screenshot from Excel below, which includes a blank cell wherever a phrase has been removed).
Here is my
Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
Dim lines() As String = TextBox1.Text.Split(vbCrLf)
[Code]....
Why is it not "blanking" the entire line in ALL cases where the line contains more than 25 characters?

VS 2010 Removing Line From Either String Or Textbox
Aug 3, 2011I have strMyString that contains about 5000 lines of data. There are some lines of data that need removing if they contain a certain string, such as "http", "www.", ".com", "cat", "fish", etc. The whole line needs removing. Each line is separated by a vbNewLine or similar.
How can I do that? Does it need pasting into a rich textbox first before processing?
[2005] Setting ForColor On Text From A Disabled Textbox + Removing The Right Bar
Jan 7, 2009As some of you are aware of, I am fairly new to VB.NET. I am trying to learn as much as I can. I have a textbox which is set to multiline. It's setup to accept a maximum of 500 characters (10 lines of 50). First of all, since it's size is fixed, how can I remove the right bar on the left as im not using it (the scrolling bar).
#2, once a user click on a button, I disable the textbox and display the text. I can set the background color, however it looks like when the textbox is disabled, text is gray and can't be changed. A fix I found is to use a label and hide the textbox, but are there any easier way ?

View 2 RepliesExit Grid With Ctrl-TAB When Grid Is On A Tabpage (onkeydown Works When Grid Not On Tabpage)?
Jun 2, 2010winforms .net 3.5 Ultrawingrid 9.2 In my subclass of Ultrawingrid.Ultragrid :
[Code]...
This works fine. But when the grid is dropped on a TabControl tabpage, the ctrl-tab looks very different to the sub above. e.keycode is seen as controlkey {17} I realize that by default cntrl-Tab moves between tabpages. I need to override this behavior. My thought is I probably need a subclass of the tabControl which will pass the keycombo through just as the form does but I confess to being clueless as to how to accomplish that. I tried to override the onkeydown of a tabcontrol subclass and just issuing a return and not and base call to onkeydown if the ctrl-tab combo was pressed but it seemed to see the e.keycode as controlkey as well.

Regex - .NET: Manipulating TextBox Input: Dash Every 5 Characters And Removing Special Characters?
Dec 21, 2011Essentially I am trying to replicate the Windows 7 (In-Windows) activation key TextBox form. The Form where it will auto capitalize letters, remove or deny all non alphanumeric characters except dashes every 5 characters that will be auto-input.I assume this can be done with a fairly complicated replacement Regular Expression but I cannot seem to create one to fit the needs.
This is an Example of what I have right now, but it creates an infinite loop as it removes all characters including dashes, than adds a dash, which changes the text and removes the dash again.

It would be great to have a little button at the end of each tab that you can click to close the tab, like in google chrome (I have an attachment, something as close as possible to that. like this is a normal "tabpage button"(the button where you click to show whatever is in the tab) [Tab Text.... ] and I want something like [Tab Text....
