Allow Gridlookupedit Control To Search Only After Typing Two Characters?
May 26, 2011
I am using third party tool "gridlookupedit" of DevXpress in my application. I have loaded the gridlookupedit control on the key Down event of it. Now if i type a character "A" the dropdown gets loaded with all values starting with "A". Now a step ahead i want to load the GridLookUpEdit only after two characters. for rg: the control must load values only when user types any two characters. If user types "A" it should not load. if user types "Ab" then the control should be loaded by the values starting with "Ab".

When I typed Private Sub cmdAbc_(Click) and pressed Enter key the first 12 characters erase leaving cmdAcc_(Click) and the cursor on the next line. Then pressing the up arrow or space bar restores the erased characters. This problem makes coding a program impossible. Programs I created before the problem arose do run successfly, but the code for those programs displays with missing characters.

I currently have a DevExpress GridControl where one of the columns have a GridLookUpEdit assigned under ColumnEdit. Yet when I run there is a column name (the display member) that shows up.I know with a LookUpEdit you can set the column headers to invisible with lookupedit.Properties.ShowHeader = False but I have no clue how to make it invisible for the GridLookUpEdit.

Is there a built in way to know when a user is done typing into a textbox? (Before hitting tab, Or moving the mouse) I have a database query that occurs on the textchanged event and everything works perfectly. However, I noticed that there is a bit of lag of course because if a user is quickly typing into the textbox the program is busy doing a query for each character. So what I was hoping for was a way to see if the user has finished typing. So if they type "a" and stop then an event fires. However, if they type "all the way" the event fires after the y keyup. Like measuring the time since the last textchange event and if it was > than a certain value then it would proceed to run the rest of my procedures.

Framework: .Net 2.0

Following is the format of the data stored in my arraylist.
A-Amsterdam
B- Brussels
C-Canada
so and so forth. I wan to search my array list by passing just the first few characters till '-' So if i have something like AA-Test then i want to pass just 'AA' to check if it exists or not.
I know that i can use contains or binarysearch but it does not serve my purpose as they both compare objects.

SELECT ContactID, FirstName, LastName, Male, Female, Email, Address
FROM Contact
WHERE (FirstName LIKE @FirstName + '%')
The above query works and returns values on first names that begin with whatever item I type in a text box.
How can I modify that code to search for items containing specified characters instead of just searching for items that begin with the specified characters. I would still need to use a wildcard because it is a search field. see below for an example
For example can I query the FirstName column to display people who's name contain the letters "an" in that order a before n but anywhere within the word e.g.
- Anna
- Jane
- Samantha

I have written a program that uses an array of the english alphabet and Morse code. I also built a form with a input box for the alphabetic information and an output box with the Morse Code. What i am trying to do is basically type a word like "Hi" in the input box and produce the Morse Code equivalent in the Morse Code output box. [Code] This works but only one letter at a time. Do i need to Parse the string of characters one at a time, and then run it through a loop like i have created?

I have an app that I have been recoding in vb.net formerly written in VB6. In this app I use some ASCII control codes such as ACK NAK ENQ US RS EOT. The VB6 app uses the CHR() function with the proper ASCII codes to handle these but in recoding I would like to use something more meaningful and descriptive than CHR(4) for example.

I've written a piece of code that takes 3 fields from a database and writes out the 3 added together, but with the middle field cropped down, so that the total number of characters is always 28, what I thought was the width of my listbox. I realised when I debugged though, that the listbox was docked and grew or shrank depending on the size of the screen.
Is there a way to determine how many fixed width characters will fit in a control, at run time?

I have some code which displays data in a hexadecimal format, so each line of the display looks like this ...
000000 xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx cccccccccccccccc
... where the left six characters are an offset and each xx represents one character and the string of cs on the right are the actual characters.
I've learned that I have to keep control characters out of that string of cs or the display gets messed up. I've been using this code and it works fine (when it's not commented out). (binbuf is a Byte array)
'Select Case Convert.ToInt32(binbuf(i)) < 128
' Case True 'traditional ASCII character
' If Convert.ToChar(binbuf(i)) <> " "c Then

What I'd like to do is write this to a DB as-is by adding wholeThing as a parameter using to SqlCommand.Parameters.AddWithValue, but all of my painstakingly-inserted newlines go away (or appear to).
I saw this and was hoping I didn't need to concern myself with CHAR(nnn) SQL stuff.

I wrote a VB.Net application that displays HTML help files according to user's search results.A user types some keywords and receives a list of HTML help files containing these keywords.When a list item is selected the HTML file is displayed in WebBrowser control.The problem is that I cannot mark the keywords in the displayed HTML file. I need to highlight them like in a standard Help. I tried many options and nothing works.If I change HTML element style manually (background color for a specific string) all pictures attached to this page are not displayed. After "Refresh" operation the pictures are displayed but the text selection is not enabled.I hope there is a standard function for this operation but I cannot find it.

I am using a Microsoft Chart control (system.windows.forms.datavisualization.charting.chart) in a Windows forms application, vb.net 2008. I use folder paths for the x values in a pie chart. Chart control converts a name like c:ewfolder into c:[newline]ewfolder. I tried adding a slash, making it c:\newfolder, but this only changes it to c:[newline]ewfolder. Is there a workaround for this behavior?
some code:
Chart1.Titles.Clear() : Chart1.Titles.Add("Largest Folders in " & txPath.Text)
Chart1.Series(0).ChartType = DataVisualization.Charting.SeriesChartType.Pie
Chart1.Series(0)("PieLabelStyle") = "Inside"
Chart1.Series(0).YValueType = DataVisualization.Charting.ChartValueType.Double
Chart1.Series(0).XValueType = DataVisualization.Charting.ChartValueType.String

I am trying to create a viewer for files with large (sometimes over 2,000 characters) records. I want to use the rich text box control and show a given record in rows of 100 characters each. I have set the font to Courier New and sized the RTB appropriately to show the records correctly. However, if there is a record with 80 consecutive alpha characters followed by a space, then 120 consecutive alpha characters, the RTB separates the line at the space, as if there were a vbLF there. This happens in other cases, but I haven�t been able to figure out how the RTB decides when to break the line.

I'm creating a search control where searches can be compounded. So, for instance, I could create a search for Orders where OrderID = 1232 or OrderID = 2343 and OrderID <> 23435
So I have a button that users can click to compound. Obviously its a complicated problem to do well, but in any case, on my path to trying to find the best way to do it, I wanted to create a variable that could be either '=' or '<>' depending on the value of some other variable set elsewhere.Is there a way to do that? Or do I have to switch to Expressions?
