Jan 13, 2011
I have a scenario in my vb.net project.I have 70 textbox in my form and planing to save it in the database using access.It's hard to explain y is there 70 textbox there but i will just draw it here [code]5 in the column X 14 in row = 70 Textboxes.What i did is I place all the GRAVEL textbox in the table batch with the attribute name GRAVEL by using a string name called GravelLin.[code]I manage to save the text in this manner txtg,txt2g,txt3g,
1. Since the save data in my table in the database is separated by comma, I know how to extract it and place it in there designated textboxes, but im thinking, or my mistake, its a very long code.Is there a way i can make my code not that long??
2. Is there a better way to save my textboxes? in a way that my code will not that long.

I have a program that I designed that scans my music folder, gets the id3 information, and then in turn inserts the results into a dataset
Here is what I have:
MusicLibrary.sdf with a table called MusicLib
MusicLibraryDataSet
MusicLibBindingSource
MusicLibTableAdapter
DataGridView
So far here is where I am, if I open the database through the visual studio ide, I manually put in a few songs just for testing purposes. When I run the program the DataGridView displays the data I entered. However I can't seem to figure out how to actually programatically add songs to the database. This is what i did so far:
I execute this command for each song scanned:MusicLibraryDataSet.MusicLib.AddMusicLibRow("FileName", "Artist", "Album", "Title", "Track") Then when done execute this command:MusicLibraryDataSet.MusicLib.AcceptChanges()
After I do that how do I then insert these items into the sql database itself so that the next time I load up my program the info is there. I have plenty of sql experience, but am used to doing all this in asp.net, i've never quite gotten all the table adapters and stuff.

How can I save a file to a folder on a network drive. I have the drive mapped on my pc as "G:" but someone else could have it mapped as "Q:" or something. I can save if I use "G:ServerNameDriveNamefolder"; but can't from another pc unless I change the code to what the drive is mapped to on that pc.
Here is the code I'm trying to use to direct to the folder with out using the mapped drive:
Code:
Private Sub Button9_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button9.Click
FileOpen(1, "\ServerNameDriveNameFolder" & filenamec.Text, OpenMode.Output) 'location of the file.

I'm running into a slight problem with an SQL INSERT INTO statement. I've tried setting this up first as a command statement and now as a stored procedure. When the process runs it's not signaling any errors and it appears that it's working properly. However when I check the database nothing new has been added. I have the statement within a try catch and it's not catching any errors. I've gone so far as to delete the table and recreate it, still nothing. I should also point out that this entire statement was essentially a copy & paste from another program that's working perfectly.
vb.net code below
Code:
Try
Dim cmd As New SqlCommand
cmd.Connection = con

I want to move my programs and the database to another computer and hard-disks. It looks to me as though I nearly have to re-create the controls and rewrite some of the code to make it so the programs still work after the move. At least with ODBC all I would change was the DSN definitions external to the programs. Is there an easy way to move or rename a database without loads of work?

I am trying to copy a table from a network database to a local database. I used DAO and could check if the network table existed using a function that tried to assign a TableDef object to the table in question. If there was no error then I assumed that the table existed and the function returned true...Or it would error out and return false.I could then proceed with the copy or not as the case may be.I am converting the code to ADO.net and need to know how to check for a table.

Recently working in vb 2010 express. I'm using service-based database which is based on SQL Server. This database will be deployed at the server. Is it possible that multiple vb.net programs, which are installed in remote computers or client computers in the same network, connect to this database simultaneously? Does the service-based database support multiple connections?

I made a query for inserting a value from text box to MS ACCESS db
sql = "INSERT INTO Equipment (port_number,display_name,equipment,tonnage,user_privilage) VALUES (" & CLng(txtPort.Text) & ", '" & CStr(txtDisplay.Text) & "', '" & CStr(txtCA.Text) & "', " & CLng(txtTonnage.Text) & ", '" & CStr(cmbUser.Text) & "')"
Actually I meant for inserting the data entered in the text box, but now saving is the code itself i,e; in port_number column 'CIng(txtPort.Text) ' will be saved

I am trying to save the information that I type in some textboxes to a textfile at the the moment I am using the IO.File.AppendAllText to write the information to txt file. When I press the button the information is added to my txt, but when I close my form the information disappears it doesn't save. I have tried using the SaveFileDialog but it doesn't work.
Is there a way that I can save the information that I type in the textboxes to automatically save when I press the button on my form, and make the information save to my txt file when I close my form and the information still be on my txt file when I open the form again The reason that I am using the appendalltext is because I want to add information to the txt file not replace the information that is already on the txt file

I have a form that display's 5 text boxes for student names. Each student names has 5 text boxes to the right of it, the text boxes to the right are for 5 test scores to be inputted. I need to save the values of every one of the text boxes to 2 array's that are declared in a Basic Module, (this is my first application that uses multiple forms) but the values need to be saved not when a button is pressed, but when the user changes the text in the boxes.

I'm using a DataGridView object that i populate using a series of datagridview.columns.add("xxx") and DataGridView1.Rows.Insert(0,"xxx")
I would like to create a text box that would filter the datagridview accordingly for a given column.
example: i put 'jeremy' in my text box and it returns only the row(s) with jeremy in the 'name' column.

I can filter when I'm only checking with one textbox, but when i try to use multiple text box filters its does not work the way I want it to. I understand what is going on here but i don't know what to do to fix it. Basically I have my main form with the datagridview, there is a button on this form called filter. When the user will hit this button a small form will pop up with 5 text boxes, I want to give the user the ability to enter into any text box they wish and the datagrid view will update accordingly.The problem is when they enter into one text box it works fine, but when the try entering into a second test box the filter is only filtering from the original datatable and now the dataview.
Code:
Public Class Form2
Dim dvFilter As DataView

How would you make a text box that guessed what you were about to type?...Don't understand what I mean?...for example, look at the Google search box...when you start typing stuff there, previous searches pops up underneath right? How would you make one of those? Would you need a text box to type things in and then a list box that pops up? All the info that pops up is in a database.

My windows form as a bunch of textboxes on it that basically let the user put in different positions/forces that a test cycle then uses. I am trying to let the user save their profile settings/open the settings so they don't have to input the same values every time they want to run the same test. Here is my code so far. basically, when i save my csv file, and open it, all 6 textbox values are plopped in the first textbox instead of being distributed to their original boxes. I just read about a "split" function
code
Private Sub SaveProfileToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveProfileToolStripMenuItem.Click
SaveProfileDialog.ShowDialog()

Okay, that snippet made the file I was trying to open in the %USERNAME%AppDataLocal folder worked perfectly, again, many thanks - But now I'm 3/4 of the way through my program, and I've hit a wall - I have the exact same program I made in VB6, and it works to perfection, but I am TRYING to switch over to .NET, and am finding a lot of difficulties in getting certain things to work - My biggest headache right now [ Which is basically the finishing of my program ] is a bit hard to explain, so this may be a rather long post: One of my programs that I use to keep track of my Music hard drive outputs to an XML file, in which there is one line I would like to be able to 'Replace' through the program I am making now to a different user-defined string, and close [ Applying string change/save ] the XML file. I have my Main Form, a TextBox1 [ I can't get the XML to open in a ListBox like I wanted ], TextBox2, a 'Locate String' Button, a 'Modify' Button, and an Exit Button. I open the XML file with this in my Form1_Load event into my TextBox1:[code]
The <DateValue> is the line I want to be able to modify [ Which the entire string looks like this: <DateValue>2010-04-10T10:00:03.5009756-04:00 </DateValue>, and I want to be able to change the date and time to whatever the user specifies ], which once the XML is loaded into TextBox1, when the 'Modify' Button is clicked, that string is then loaded into TextBox2... This is where I am lost - How can I apply the modified string to the TextBox1.Text [ Entire XML file ], and save it upon program end, without the rest of the XML lines being disturbed? I realized I needed another Button - The 'Modify' Button now loads the selected string into TextBox2, and I have a 3rd Button to 'Apply Modification', which I want to update the <DateValue> string in the TextBox1 [ Full XML file ] from the modified string in TextBox2, then save on exit - Hope this helped clarify things.So here's the routine:
1. Form loads, opening the XML file, and loading it into TextBox1.
2. User clicks 'Modify' Button to load searched string into TextBox2.
3. User modifies TextBox2 entry.
4. User clicks 'Apply Modification' Button, which changes the searched string in TextBox1 to the modified user-defined string.
5. User clicks 'Exit', which saves the XML changes from TextBox1 [ Without messing up the XML file format ], and the program ends.
