IDE :: VS 2005 IDE Does Not Recognize The Table Adapter In Code?
Mar 23, 2009I copy/paste one datagridview from one form to another (different solutions) using two instances of VS 2005.The target form has the datagridview with all settings, including the DataSet and tableAdapter used by the original form. The datagridview also has all old settings. Everything is fine, it works as expected, with one drawback: every time I make any change in the target form surface, VS tells me that the dataset and the tableadapter are not defined and no longer loads the form in design mode giving errors mention that the dataset and the tableadapter are not defined.To be able to view the form surface in Design Mode, I have to edit the form.Designer.vb file and replace the references to the dataset and tableadapter as follows
View 1 RepliesDB/Reporting :: Creating Access Table Code [VB 2005.NET]?
Jul 5, 2008I'm looking for some simple code that lets me create a Microsoft Access table via code.Currently all I do in Access is write and retrieve data from specific tables but now I want to be able to create them at runtime. Here is an example of the code I use to load some data just so you can get a feel of what I'm currently doing. Hopefully there is an easy way using the same rough way that I'm currently dealing with databases.

Truncate String Value To 17 Characters Only?
May 19, 2010how 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.
Truncate The Beginning Of A Log File In .NET?
Feb 24, 2010I 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.
VS 2008 : Don't Use Int() To Truncate Numbers
Oct 4, 2009I'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.

Loop Does Not Truncate Into A Two Decimal Place Holder
Feb 14, 2012I wrote a loop that posted an accrued principal cycle to a listbox for a period of 10 years (10 loop cycles). The problem is: not only does the amount of the principal reconfigure for each loop cycle, but it does not truncate into a two decimal place holder as it should. I would like to use the ("F2") but I am not sure where to put it within the code. Here is what I have for the Calculate button event handler.
