ComboBox Set To OwnerDrawVariable Causes Item Text Mis-encoding End Displaying Blocks?
Apr 30, 2012
I have a problem with combobox. I set the DrawMode into OwnerDrawVariable so I can draw items seperately with styles, but the characters of the items are now displaying blocks. The block characters are none ASCII. It used to display well but not now and I don't know what caused it to happen. I didn't change my system locale. At the same time, other combobox that have Normal DrawMode displays nicely fine.
My custom drawing code:
e.Graphics.DrawString(combo.Items(e.Index), combo.Font, b2, rect.X, rect.Y)

How to display text in a rich text box when an item is selected in a listbox. Here's a snippet of my
Private Sub radGunsNRoses_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles radGunsNRoses.Click
'Declares songs into variables
Dim strSong1 As String = "1. Sweet Child O' Mine"
Dim strSong2 As String = "2. Novemeber Rain"
Dim strSong3 As Integer = "3. Welcome to the Jungle"
'Band Picture
[Code] .....
What I really want is that when radGunsNRoses is checked, the listbox displays the songs and when one is clicked, it shows the song's lyrics in the ritfSongs. Same thing goes for radACDC but the songs are different and the lyrics.

I've been testing an application I'm working on in Windows 7, Vista and XP. If I'm using XP then I get a couple of solid black blocks after the items listed in the ListBox. They are absent when running the same application in Vista or 7. I have the enable application framework checkbox unchecked. I haven't tried changing that to see if it makes a difference.

What I to do is really simple. I want to add a group of text boxes in my VB net application. note that the number of text box only can be known at run time.
I want to give default value to this group of text boxes. At run time, users can input text and change the text for each item.
How can I do this? Is there a control to do this?
What I can remember is ComboBox control. However, I only can display the item text and do not know how to change the text for each item.

I have this code for an ownerdrawn list box that is repainting too frequently. It seems to be related to trying to scroll an event with a different height than normal.

Using 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

My text file is a settings file and I know I will be adding more to it in the future, right now it reads "autoplay=false;mintray=false;"I am currently using probably the most inefficient way to check both of those settings:
if contents = "autoplay=false;mintray=false;" then
elseif contents = "autoplay=false;mintray=true;" then
elseif contents = "autoplay=true;mintray=false;" true
elseif contents = "autoplay=true;mintray=true;"
endif
How can I read the file, find each word from the equals sign to the semicolon, and store each of them in a variable identified by the text before the equals sign? Something like this:
contents = "autoplay=false;mintray=false;"
autoplay = "false"
mintray = "false"
Also, how can I edit the settings in the text file without having to overwrite everything every time I save to it? For instance; finding mintray in the text file, and changing mintray to true instead of overwriting the file with "autoplay=false;mintray=true;".
This is my current

I'm developing an app for WP7 and Win7 that will get info extracted directly from particular websites. The app will download the HTML source and parse through it to find the required strings. The strings may not have tags. note multiple instances of the string needs to be found. I've tried a few very rudimentary ways, and although they work, they are extremely slow.

my program downloads into a combobox every item(line) that is in a text file located on a server.
Every line in the text file ends with "a)" or with "g)".
Now I just want to make 3 radio buttons:
- one that will allow the download in the combobox only the item ending with "g)"
- one that will allow the download in the combobox only the item ending with "a)"
- one that will allow the download in the combobox of both (I already know how to do).
How can I do so?
To download the entire list in the combobox I do:
Dim List As String = client.DownloadString("http://mywebsite.com/mytextfile.txt)Dim lines As String() = List.Split(New String() {ControlChars.CrLf}, StringSplitOptions.RemoveEmptyEntries)ComboBox1.Items.Clear()
ComboBox1.Items.AddRange(lines)

I am new to vb.net and I am using visual studio 2010. I have two comboboxes on a form, each combobox is set to DropDownList so that a list of items can show in the combobox, but no text is allowed to be entered.
For combobox A, if user chooses item 1, the list of combobox B should be updated accordingly. I think this is quite common on a lot of applications. But I do not know to implement it. I even do not know the keyword to search for the relevant property or event handler.

I have done very little with encoding of Text. Truthfully, I don't really even know what it means exactly.
For example, if I have something like:
CODE:
Is that 'encoded' in memory in a particular format? Does that format depend on what language I'm using?
If I were in another country, like China, for example, and I had a string of Chinese (mandarin? My apologies if I'm using the wrong words here) would the following code (that I've used fine on English strings) still work the same?
CODE:
Or would it lose all meaning when you convert that .Net string to a UTF8Encoding when that conversion isn't valid?
Finally, I've worked with .Net for a few years now and I've never seen, heard, or had to do anything with Encoding. Am I the exception, or is it not a common thing to do?

I have an app that I am developing to keep track of my members' names and phone #'s. I have all current names and numbers in a csv file and they are read into a structured array. The app can add, delete, and modify members. I have everything coded except the 'Modify' menu item. The list box is populated with only names at run time, I would like to have both the name and phone number displayed in the two text boxes I have on the form when a name is selected from the list box. I can get the name to display in the text box I have for names, but since the phone number is not in the list box I am wondering how I can get it into the appropriate phone text box. I used txtName.Text = lstMemberList.SelectedItem to get the name displayed but since the phone number is not in the lstMemberList list box I cannot figure out how to get it into the txtPhone text box.

I have an ASP.Net app that allows a user to write text into a Telerik RadEditor control and then send an email.For some reason I'm sometimes getting strange characters showing up in the email that is generated.se if I use the later, the text would show up just fine. If I pull up the saved record within the ASP.Net apps interface it looks just fine. It also appears just fine when I view the text within the recorded of the MS SQL table it was stored in. Continued--->I have tried to add it to the constructor of my email class with/without mybase but that had no effect.
Public Sub New(ByVal EmailDate As DateTime, ByVal LogoPath As String)
