Using tabs for my web browser, I noticed (since im using documenttitle to populate the tab text) if a site has a long title, it will extend my tab var far, how can i limit this to a certain amount of text?
tab text code it:
TabControl1.SelectedTab.Text = CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).DocumentTitle
I've been trying to find a solution to this problem all morning.This is what I have: 1 comboBox control,autofilled from SQL table [code]...
View 6 RepliesI've been using it and even saw a method in a MSDN search given that suggests that it should be used but have found that there are defects using it. An example of problem occurring.
Dim db As Double
db = Int(10.12 * 100) / 100
db should be equal to 10.12 but the result you get will be 10.11. In the above example nothing is being truncated. If you added some digits right of the 2 it would give a good result. But if you're using a variable and it sometimes is equal to 10.12 or 9.12 etc. then a problem would occur. Also if 10.12 was replaced with 10.03 you'd get a result of 10.02. 10.04 gives a result of 10.03. 10.2 gives a result of 10.19. I'm now using code such as what is seen below instead of using Int() :
bd = Decimal.Truncate(CDec(10.12 * 100)) / 100
You could declare bd as a Decimal and then you wouldn't have to use CDec(). If I try Int(1012) the result is 1012 but Int(10.12 * 100) will give 1011. Pretty weird in my opinion.
I was wondering if there was a solution to replacing the tab control's tabs with custom tabs made in Photoshop. I know there are plenty of super expensive programs that can do it, but I was wondering if there was a way to do it programmatically. I was thinking that maybe it could linked in some way with a .DLL?
View 1 RepliesMy code is basically a file parser/editor and it handles most files fine as they hold a handful of records concerning family members. However there are a few files that crash when trying to deal with them. Here is the problem.Each family member record creates 3 tabs that hold an average of 3 group boxes each. Each group box holds an average of 3 text boxes.So each member record creates 3x3x3 = 27 text boxes and some files get up to 289 family members which = 7803 text boxes.
The problem is the rare file with 400+ member records = 10,800 text boxes which causes a crash due to using up all the window handles. Each member has a separate tab page (with 3 subpages) but really only a dozen or so member pages are visible in the GUI with scroll arrows to move through them so I was thinking of somehow making the GUI a scrollable window so the tabs get built, displayed and disposed as the user scrolls left and right through the member tabs.
The files are parsed into a 3d list DataList(x,y,z) where x is the page number, y is the group box number and z is the text box number. So all the data is available. The code then traverses MyList and builds GuiList(x,y) where x is the page number and y is the groupbox number with all the textbox.text linked to MyList(x,y,z) locations so all text changes are reflected in the MyList.
I already have a memberCount variable and I am thinking of building, say, the first 30 member tabs with the middle 10 being visible in the GUI. If the selected tab > 20, then dispose of the first 10 tabs and create tabs 30-40.I am thinking I will keep all the member tab pages so I don't have to deal with inserts and indexing problems but just dispose all the group boxes and text boxes for tab pages out of view. I already have a deep clone sub that clones members when the user wants to add a new family member and I am thinking I will have to add something similar when a tabpage is passed in for disposal, it traverses and disposes each text box, then disposes the group box for each group box on the tab page.Additionally, another routine will rebuild the group boxes from the data held in MyList(x,y,z) when a tabpage(x) is passed in.
The issue I'm having is with the text on the tabs in my program. The tabs are set to a fixed size. When it displays the text, it's always centered. But when I add a new tab, the text on the tab to the left of the new one changes to left-align. This just seems odd and random. I feel like it's a dumb question, but how can I get the text on my tabs to always be left-aligned? I'm also curious about a way to put an 'x' button on my tabs. I really don't want to redraw the whole tab though, that usually just looks

View 1 Repliesi am building a tab control (using VS 2010 and 4.0 framework). on Tab 0, this works as expected:
Me.ddUE_B1.SelectedValue = Me.B1.Text <-- changes the combo box selection to what is in the label.
on the other tabs this does not work. when I do a messagebox to show, say, Me.Ea1.Text on Tab 1, nothing is returned.
Is there an issue with referencing controls on tabs that I am missing? In general, I will need to set combo box's value to what is in the database when the form loads.

View 4 RepliesUsing Visual Studio 2005 (vb.net) (windows forms) on Windows XP, I have a standard Microsoft TabControl.A button click adds/removes an image from 1 of the Tabs.Seems like the image is placed OVER my tab's text, making it unreadable.Why isn't it like it should be: Image on the left. Followed by text on the right.Why is the image being placed OVER my tab's text? Do I need to do some kind of "refresh" or "redraw" before it will appear as it should? I don't see any way to "make the image appear on the left edge of the tab". (NOT the tab-page.) ... and then place the text just to the right of the image. (Just like a normal image+text tab can do.)The code is pretty simple, it just gets an image from my ImageList: cfgTab.ImageKey = "PadLockClosed.png"' Show CLOSED PadLockThe tab's text changes from: This is my tab text to: T(IMAGE HERE)is my tab text The image appears OVER the beginning of my text. But if I move to another tab, then move back, the image appears in the correct position:(IMAGE HERE) This is my tab text

View 7 Replieshow to truncate my string value to 17 characters only.
in my program, the acceptable number of characters for First Name is 17. Characters more than 17 should be truncated but it may cut words in the middle. I need to make the length max 17 characters, but, if it cuts a word, it should also remove this half-word completely.
I have an VB.NET app that writes the status to a log file in text format. Over time, the file is getting large and I wanted to know if there is an efficient way to truncate the beginning of the file.
To make things easier, I am looking to specify a file size (say 2-3 mb) and I am writing the log using a StreamWriter:
Using strm As New IO.StreamWriter(filelocation.log, True)
strm.WriteLine("msg to write")
strm.Close()
End Using
I thought about using the strm.BaseStream.Length to determine how much of the file to cut off, but by using the .SetLength it would cut from the end - not the desired result.
