Convert String To SqlDbType?
Jan 27, 2011
I am trying to convert a string values into a SqlDbType. My code is able to covert "Text" into SqlDbType.Text without any errors but when I try to convert "bit" into SqlDbType.Bit, I receive the following error: "Requested value 'bit' was not found."The same thing happens when trying to convert "int" into SqlDbType.Int Error Message: "Requested value 'int' was not found."Why will this work for "text" but not "bit" or "int"?
Dim MyType as String = "bit"
Dim sdtype As SqlDbType
sdtype = DirectCast([Enum].Parse(GetType(SqlDbType), MyType), SqlDbType)
[code]....

I didn't like how the SqlCommandBuilder generated it's Update command, so I'm making my own with the following code.. This is a large table and I didn't want to get a concurrency error just because I changed field A a few seconds after someone else changed field F.It works great but as you can see I manually have to exclude the Memo field because this is a TEXT datatype field and so you can't use WHERE for that.
Is there any way to get the sqlDbType for each field so I can use this procedure to easily generate all Update commands I need? I have tried GetType but that returns String for this field..
Dim strUpdates As String = "", strClause As String = "", strColumn As String
Dim dr As DataRow = dsDemo.Tables("demo").Rows(bsDemo.Position)
Dim sqlCmd As New SqlClient.SqlCommand("", frmMain.cn)
For i As Int16 = 0 To dr.ItemArray.Length - 1
strColumn = strColumn.ToString.ToLower

For no apparent reason, I'm getting an exception on this line in my when the table adapter attempts to fill my dataset.
Me.TblFuelTableAdapter.Fill(Me.CCFuelDataSet.tblFuel)
The error reads:
Quote:
System.ArgumentException: No mapping exists from DbType Object to a known SqlDbtype.
This error just came out-of-the-blue. If I 'Preview' the data though the DataSet directly (using the Fill() query), the data returns fine...

I'd like to convert a string which contains a decimal number into string that contains the binary value, the octal and the hexadecimal value of that decimal number.Afterwards I also like to convert a string containing a binary, octal and hexd. number into a decimal string.Basically I'm looking for the functions:
dec2bin
dec2oct
dec2hex
bin2dec
oct2dec
hex2dec
I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.

Currently, I'm using the following code to pull info from the management class.
[code]...
I'm also pulling info from the bios, disk drives, video, etc. What I've noticed, is although it runs fine on my pc, it may error out on some pcs since it is hardware dependent.I'm having trouble implementing a check to find if it exists before I convert to a string and add it to my overall string.

I'm working on a mass text replacer program because I'm sick of all the 10-day trial ones out there that aren't very good.The entire program is basically finished (All easy stuff), but now I need to code the actual replace/delete stuff, which I'm stuck on because apparently the way I originally intended to do it is not possible.
The way it works is you load a text file (.txt, .cfg, .ini, .doc, etc.) which opens a StreamReader which writes all the data into a listbox. Then you pick whether you want to replace or delete a string. If you select replace, then you enter the string to search for and in another textbox you enter the string to replace it with.
The way I originally intended to do this was like this:
If o1.Text = "Replace" Then 'The option
Replace(txtfile, str1, a1) 'txtfile is the data, str1 is the string to find and a1 is the replacement
End If
The problem is, I believe this method requires txtfile, str1 and a1 to be strings, but they're all 1-dimensional string arrays, which cannot be converted to strings, or at least I don't know how to convert them.
A friend told me one way I could do this is to open both a StreamReader and StreamWriter and do the replace/delete line by line as they are entered into the memory and write them to a temporary file which is then copied over the original. I can do this kind of, but I still don't know the proper way of doing the actual replace code because the string to find and the string to replace with are still 1-dimensional string arrays rather than strings.

Value of type 'System.Func(Of String, String)' cannot be converted to 'System.Converter(Of String, String)
Why? They are both effectively a function pointer (or delegate?) to a function that accept a string and return a string.

I have 1 string of 12 numbers separated by a ',' "11.11,22.22,33.33" etc coming in my serial port. One number has so far been 5339, but now its changed to 533d, which causes problems, for reasons I am still trying to work out.
The top numbers are all real numbers ie 0.000 or 00.00 or 000.0, whereas the bottom 3 numbers are Hex FFFFF but just happen to show decimal numbers by 'good luck'.[code]....
