VS 2008 Write Special Chars From Database?
Apr 5, 2011
I have a database where the data contains some special chars. I retrive the data from the dbase (dbf) file with a sql statement and write it into a text file using vb.net. When I write the text file some of the special characters are not written the same way as in the dbf file, its written as a box. I'm using:
Using sw As StreamWriter = New StreamWriter(dbfFile, False, System.Text.Encoding.Default)
while writing to text file. I'm not sure how to read the exact data from the database.

I solved this issue in this thread but there still are issues with special chars. ie 'I thought by doing parameters that it would take care of any special chars for you. Well i am still getting mysql exceptions about syntax. I look at the string it is working with and it has a "'" in it.Why are they not working as I expect them to?

I'm not sure what to call this so my search results weren't very helpful. I am writing an XML document that has computer paths and special chars such as '&'. XML does not like them, so I need to find a way to convert them. I looked at Apple's iTunes XML document and they have the following:Actions & Motives = Actions '&' Motives (without the ' ')C:/Documents and Settings/mmulhearn/My Music/iTunes = C:/Documents%20and%20Settings/mmulhearn/My%20Documents/My%20Music/iTunes/

I am a new VB programmer and am using TextBox in VB2008. Here are the problems I experienced in TextBox -
1, After I typed number in TextBox and found I need to type another number. So I used backspace key to remove it. But at this time program quit and displayed this problem: InvalidCastException was unhandled. How to solve this issue?
2, Can anybody tell me how to set number of characters are allowed to be typed in TextBox?
3, Can anybody tell me how to implement the feature that only numbers are allowed to be typed? In case letters are typed, how to tell user to re-type?

I was wondering if it was possible, in a console application, to write characters like "℃" using .NET? When I try to write this character, the console outputs a question mark.

In VB.net I've got the following line that removes all non-alphanumeric chars from a string:
return Regex.Replace(build, "[W]", "")
I now need to extend this to remove non-alphanumeric chars that aren't [] or _. I've changed the line to:
return Regex.Replace(build, "[W[]_]", "")
However I'm pretty sure that this says
replace non-word or [ or ] or _
how do I negate the tests for the [] and _ chars so that it says
replace non-word and not [ and not ] and not _
Some examples:
"[Foo Bar_123456]" => "[FooBar_123456]"
"[Foo Bar_123-456*]" => "[FooBar_123456]"

Is it possible to create database queries on the fly with VB?
For i = 0 To (UBound(WeekNo) - 1)
For NLoop = 1 To 50
WeekRow(NLoop) = WeekSinceLast(i, NLoop)
Next
Next
I want to write each WeekRow to the database for each week (= i). WeekRow contains 50 elements, each of which needs to be placed in a separate field.
So, can I generate a SQL query that is constructed on the fly? If so, how do I go about it?

I'm trying to make buttons that will open each of the "special folders" in Windows Vista. Here's an example:
Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click
Process.Start("explorer.exe", Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments))
End Sub
As you can see in the above code, the button will open the Documents folder. My problem is the only folders this method can open are the documents, pictures and music folders, while I also want to open these folders below:
Downloads
Videos
User folder (aka the folder that has the user name on it)
Computer (aka My Computer in XP)
how to do that?
