Sql Server - Appending An ADO.Net Datasource In Winforms?
Jan 5, 2011
I am working with two seperate SQL statements when user conducts a search on my winforms app.A user can search based on an OrderNumber, OrderDate, ClaimNumber, ClaimDate, CustomerID, CustomerPhone One SQL statement returns the OrderNumber (in case the user searched based on OrderDate), which is used to execute another SQL statement, which returns the details about the order.
The results are populated in a gridview.Once the first statement is executed, I have a DataSource (DataSet). How can I append that datasource to display the fields from the second statement as well, keeping in mind, that the first statement could return multiple records, all of which will need to have the appropriate order details correctly linked.

Is it possible to append text to a text file located on a webserver from a winform? If so, can you please point me in the right direction. I've searched this forum but can only find documentation on appending a local text file.

Check out the simple code below :
[code]...
What happens is that when the Item2 is selected in the first listbox, the second listbox automatically changes its selected item to the Item2. This happens just the same with the other listbox.

Let me try to describe my problems in the simplest way: I have combobox1 and combobox2. I hope to achieve two things: Combox1 is bound to list1 (a list of string). When a user selects an item in list1, list2 (a list of string) will be obtained from database and combobox is bound to list2.If user specifies text1 in combobox1 and text2 in combobox2, then these two values will be shown in the comboboxes regardless of the bound lists.
[Code]...
So the results of above code is that goal 1 is achieved, but goal 2 is never achieved. combobox1.selected index is always 0 and combobox2.selected index is always 0 too.

I have a gridview that is bound to a datasource (Windows Forms, VB.NET). One of columns is a property of type boolean, and I want to show "yes/no" in the column instead of 0/1 or "true/false". Is this possible? Can you edit displays of columns that are bound?

I normally place all db related work in my databases in SQL Server Express 2005. But in tutorials I have seen, I heard that one needs to re-create referential integrity and relationships and constraints and checks and defaults anew in datasources mapped onto databases. Is this true? What parts of a database are NOT mapped on to datasources?

Ok, so I've got this Visual Studio 2008 Project I was working with about a year ago perhaps. And this project had a datagrid that was linked to an external database running on a server off the internet. Now, this databinding was all done using Visual Studio 2008's built in features. But how can I now change the binding to a different server, without destroying the project? I've noticed that a lot of the code that Visual Studio creates makes a mess. So manually trying to change the datasource has allways f*cked up the whole project for me.
I'm not all that good with this stuff, that's why I used the built in features of Visual Studio. But I noticed that several things appear, like a binding source, and a dataset. Is it possible to do this? Perhaps even better, making these settings be controlled after the program has been compiled. The way it is now, it's all hard coded after compiling, and that kinda sucks. I remember trying to do this about a year ago, trying to bind these settings to variables stored in settings. But I never got that to work. Just throwing around ideas here

I want to connect a database that is located on centralized server. How can I use a windows form VB.NET application to access it? Is this possible?
How can I maintain a single user entry (e.x== used of INSERT command)?
Are both of the above things possible? If so, how can I go about implementing them?

I do have Visual VB.NET 2008 Express installed, SQL Server 2005 express installed, and I do know how to start a brand new project in VB.NET, and then add the database to the solution explorer, modify the tables/fields, etc. I know how to create a WinForm, add some controls (and name them and whatnot).....
So in MS Access I know how to use VB in the Code-Behind-Form to use the form in an unbound manner, and insert data into the tables via Visual Basic with SQL statements. I am looking to be able to begin the same sort of thing here, because I guess I have to start somewhere?

I am trying to add multiple files to FTP server by dragging and dropping and I am able to do that using try catch block and if we give the ftp settings correctly it takes 1 sec to upload them but when we give wrong details it hangs up and dosen't give me any error message though If I give an exceptional message.
Now I am getting error message as well as success message for every file I add.I do not want that to be happen.where should I give messages for success and failure so that it should take few seconds for uploading and if not should give me a message immediately.
Here is my code:
Private Sub uploadFile(ByVal FTPAddress As String, ByVal filePath As String, ByVal username As String, ByVal password As String) 'Create FTP request

I have a VB2005 winforms application that will loads city data from my database table. This is to ensure that the user enters the correct city spelling, in order to receive an accurate quote. Currently, there are about 150K cities that are being loaded to the dropdown listbox on page load. It takes about 30-40 seconds for that page to load. My initial thought was to allow the user to select the state first. Then load the city values. But the user has the option of going back and requesting a quote for a different city / state.

This is my first attempt at creating a Winforms application, and I have been developing in the .Net Framework (Silverlight, ASP.Net, WPF) for about 6 months. So, my appologies if this is a newbie question.
Basically what I am doing right now is taking the drawings of a stylus-based input, and storing them into an image field in a SQL Server database. Then, in another form, I go and get that image out of the database, and load it into a picture box. It works, but it is rather "sloppy" how it got there.When the user clicks save, it stores that image into a temporary folder, then converts it to a byte array and throws it into the database that way. Then, it deletes the file from the temporary folder. When retrieving it, it pulls it out of the database in a byte array, then converts it to an image in a temporary folder, thus displaying it on the form.
Is there a way that I can just bypass the storing of the file onto the user's harddrive both times, and go from byte array to picturebox?

I hope I got all that in this question title. Let me explain. We are starting on small desktop app that will snowball into a big app with many forms. The database is SQL Server. It will have classic stored procs/functions performing classic CRUD functions. Given a table or stored proc in SQL Server what is the quickest way to create a form with all the hooks to maintain a table.
For e.g. lets assume I have table like this (most code below is pseudo code)
Table Employee
{
Name varchar(30)
DOB Datetime
Address varchar(100)
}
From this as source I want to create my Target which is form with 3 labels and 3 textboxes with add delete modify buttons (or OK button to add if not exists or modify if exists)
[Code]..
The code generation tool or technique that will be used should generate the correct db hooks (create SQL parameters, SqlCommand, execute sql.. basic try catch etc. Is there any open source tool to do this ? Some trick or templated approach via VS 2010 ? Worst case any third party tool ?

I am trying to use and display calculations from various text fields, however it is appending the values. I think it has to do with it being a String Variable and not a Value.. here is the code
Private Sub btnTransact_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTransact.Click
If rb1Deduct.Checked = True Then txtp1Amt.Text = (txtp1Amt.Text - txtTransact.Text)

I have a list of file names and there locations as follows:
c:ICTAUTOCAD_2010Customisations2009040920090409.lsp
c:ICTAUTOCAD_2010CustomisationsAdvanced OffsetLSPADVANCED
OFFSET.lsp c:ICTAUTOCAD_2010CustomisationsLockDWGLSPLockDWG.lsp
c:ICTAUTOCAD_2010LSPacad2010doc.lsp
The list is very basic but should be appended to say:
(load "c:ICTAUTOCAD_2010Customisations2009040920090409.lsp")
(load "c:ICTAUTOCAD_2010CustomisationsAdvanced OffsetLSPADVANCED OFFSET.lsp")
(load "c:ICTAUTOCAD_2010CustomisationsLockDWGLSPLockDWG.lsp")
(load "c:ICTAUTOCAD_2010LSPacad2010doc.lsp")
How can this be done with VB.net?

How would I go about appending text to a Textbox without losing the current scrollbar position? I thought somehting as simple as:
Textbox1.Text += "MyString" & vbCrLf
would work, but it just sends the scrollbars to the top.

This append feature does not seem to work. I've looked in many places to no avail. The other examples below for writing and reading seem to be going fine.

Dim objWriter As System.IO.StreamWriter = file.appendtext("textTBD")
objWriter.WriteLine("textTBD")

I am trying to save the contents of a richtextbox to a text file. I know that they .SaveFile method automatically overwrites the existing file so I have a routine that will load the contents of the file into a temporary rich textbox control then append the new information to that and then save from the temp richtextbox. My application works as I want it to on my workstation but I cannot get it to work correctly on the notebook computer it will be running on from now on. It only works when I put in a breakpoint and I am not sure why?
[Code]...
If I put breakpoints on any of the lines rtb.Select, rtb.Copy, rtb.Paste then it works. I even tried putting a Thread.sleep before saving, thinking that more was needed to do the copy/paste but that didnt work either.

Lets assume I have a DataSet that contains the following info (columns seperated with | character):
1 | Logan | Young
2 | John | Doe
3 | Jane | Doe
4 | Joe | Soap
If I now write this info to a text file, but later want to append 5 | Susan | Sarandonto the end of the text file, I obviously want to check that the text file doesn't already contain the data that I want to append to it. I'm having a little difficulty figuring out how to perform this check...I know you'd have to loop through every row in the DataSet's table and compare it to every line in the text file. That part's easy.
