View 8 RepliesSo I'm writing this VB.NET application, and it's doing things. But whenever I press a button to start some process, it does what it does except I can't click the window until it's finished. Otherwise the whole thing freezes. This essentially stops me from doing more than 1 thing at a time, because if I click another button (or anywhere) when something's running, it just freezes my program.
View 1 RepliesI'm trying to optimize my WPF/VB.net program, and I'm considering freezing some objects. However, while I know that an object that is animated in any way cannot be frozen, I need to know...can you change the visibility of a frozen object?
View 1 RepliesI'm sorta newish to VB.Net programming, and in the program I'm working on (VB Express 2010, Windows 7) its as if everything has frozen. When I make changes to the code or the designer view, then run/debug the program, the changes don't get saved. For example, I put a random button on the form, saved it, ran it, and when I ran it, the button didn't appear.

I created a function that creates a global temporary table to stage data from a excel sheet I need the table to persist for me to map the columns using a form. The table is still there when the code goes back to the sub that calls the function until I call the form where I do the mapping. I am trying to avoid create/drop table scenario with a perm stage table.How can I get this table to persist until the data gets loaded into the perm table?

This is really a pre-defined table and the data is already specified to be inserted to the table. However, my primarily task is to read a flat file which has the data and consider the first line as the column to be column names.
Therefore, initially I created an open dialogue to browse for the text file and store the path such as E:Datafile est.txt, in a TextBox1 visible at run time. Now the task is to change the above "create table" to read the txt file (column names are on the first line) and then create the table in the database.
I'm trying to create table in my database, that would have name like i type in Textbox and than i have to click the button With code like this :
sqlCmd.CommandText = "CREATE TABLE NAME = '" & TextBox1.Text & "' (First_Name char(50))"
I'm getting erorr : Incorect syntax near "name that i type"

View 11 RepliesI am working with VB.net and Sql server 2005. I am creating a mini application to load data to a database in SQL.Presently, I have a form with a browse button where you can select the file you want to load. This file extension for example is E:DatatobeLoaded est.txt. This file extension is then shown on a text box (TextBox1) on the form.
I have another button called BtnExport. What I want to do is when this button is clicked the code reads the data in the table test.txt, and connects to SQL and creates a table. Now, by default the first line will be column names. (It is similar to the create table option you have when you import data to SQL).
The sql Connection is :

View 6 RepliesI am using vb.net to create a Word table. Everything works fine, except that it is very slow. It takes about 0.34 seconds to create each cell in the table. I am using an HP machine with i7 processor and 12 GB of RAM. At 0.34 seconds per cell, times 7 columns, times 189 rows ~ 7.5 minutes to create a small table! I must be doing something wrong, but I have no idea what it could be. The table looks looks fine.
My code looks something like this:
oWord = DirectCast(CreateObject("Word.Application"), Word.Application)
oWord.Visible = False
oDoc = oWord.Documents.Add(ClsGUIGlobal.TIMBERSCHEDULEWORDTEMPLATEPATH)

I want to create an index on my table. I used the following command Code:
cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:database.mdb;Persist Security Info=False")
cn.Open()
cmd = New OleDbCommand("Create INDEX itmno_idx ON INVENT (ITEM_NO)", cn)
cmd.ExecuteNonQuery()
Now I want to use this. Is there a file created with some extension when i do an Indexing?. Is the above statment actually index the field, ITEM_NO or do i have to use ALTER TABLE command? Currently I am getting error "Cannot execute data definition statements on linked data sources"
I have no problem creating it. I have created a yes/no (bit) field and set it's default to False. once created if i open the database this column shows data as 0 or -1 as expected. If i created it in Access it would display as a checkbox
