I am thinking of creating EXCEL File, in which I will put all the names in 1 column and call that excel File, when "dropdown" of combo box is clicked.
In a form, I have a Combobox (named cbArt) with the values: 1, 2, 3 and 4
I have a table with the fields: Id, art, name, width
I wanna put a datagridview in my form, so always I change the value in the CbArt the Datagridview shows me the fields with this SQL:
"select * from artigos where art='" & cbart & "'"
But, how can I pass the value of the cbart to my Datagridview's SQL?

Suppose I save a file as *.tar (this extension is my own making) using a vb6 program.Now when the user clicks this file, the window asks 'with what program to open this file' and he/she selects the exe of my program. Now I want to pass the name of file clicked to my program. Like when we click *.xls file, the exe of Excel program knows which file has been opened or clicked. Is there a way?

The Top code is a work around, as .net will not run .bat files due to security resaons (unatended process)
I am facing a problem now, where I need to pass a parameter to the .bat file, but because of the way it is executed in the command prompt
I want to create a file to pass to another exe. Used File.Exits and then File.Create. But File.Create returns a FileStream, so I should close the file??
View 4 RepliesI am currently still learning to use VB.Net feature. Currently I am trying to execute a .exe file where there will be passing parameters to run the script. E.g. this how it works on the command prompt line:
C:Documents and Settingsproject1>textfile.exe file1.txt file2.txt file3.txt file4.txt
Above line will be able to run the textfile.exe script.
I am using VB .Net to create a User Interface where user will be able to use the 'OPEN CLICK' button to choose the files (which will display on a textbox) and click on a 'START' button to run the program. I managed to find a code - process.start() feature, however it cant seem to work..
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim MyProg As String
Dim executable As String
executable = "C:Documents and Settingsproject1 extfile.exe"
MyProg = TextBox1.Text
Process.Start(x, MyProg)
I'm working on a VB.NET DLL right now, and one of the functions I'm writing is supposed to take a file, and clip out an array of bytes (the method I've got works, and can be abstracted away here). What's the best way to pass a file to this function? Would passing a filename to it be best, or what would be the best way to accomplish this?

case_no result
tc_1 pass
tc_2 fail
Table2 should be updates from table based on the results... If all results is PASS then the table2 should be updated as pass... if any result is FAIL then the entire case_no should be updates a s fail..
This code was working consistently, but now...This code works on the first pass.Then second pass it just hangs on Code:Dim tcpClient As TcpClient = tcpListener.AcceptTcpClient() for about 2 minutesThen the code will fork for another pass, then fail.....

View 5 RepliesPassing variables from .bat file to vbscript. I have .bat file that launches test.vbs. I need to pass variable defined in the batch file inside the .vbs file.

How would one go about sending parameters to the application? For example, I want to send my exe some switches or parameters.

Something like that. Then I can use the para1 and param2 throughout the exe Possible? But it is not command line, it is gui based.
Just started VB programming this week and have found a wealth of information about what I'm trying to do. Problem is, some of it is more complete than others.Here's what I'm trying to do:In Form1 (my main form), I want to instantiate a class that contains a couple of properties (speed setpoint and position setpoint). When I click a button, I want to pass this data to Form2 and populate two textboxes on Form2 with the properties of this object. I want to manipulate the property values on Form2 and click an OK button which closes the dialog and returns the manipulated data, updating the property values of the object. Here's the algorithm I'm following:1) On Form1, instantiate the class2) On Form1's "Pass Data" button click event handler, instantiate a Form2 object and invoke the ShowDialog method, passing the object as a parameter.
3) On Form2, overload the ShowDialog method to accept the object as a parameter and modify the method so that it returns the manipulated class data.4) On Form2, in the ShowDialog method, populate the textboxes with the class data that was passed in.Here's where I get stuck. If I press the OK button on Form2 (DialogResult.OK), it returns me to Form1, but what hook do I have in Form1 to receive the manipulated class data that the ShowDialog method is returning?Here's an example of what I'm thinking about:
Code:
Public Class Form1
Dim clsController1 As New MotionController
[code].....
I'm sure it's probably a very elementary question, but every explanation I've found seems to be incomplete.
my problem is that my company does not want to serve up the .json MIME type, so I have to use ASP.NET to fetch the JSON file from the file server. Currently I have jQuery that does a getJSON and traverses the JSON object to build certain elements of the page. Is there a way I can use ASP.NET (VB) to give the object to my jQuery script after I fetch it?

Prog1.exe is in folder1
Prog2.exe is in folder1/subfolder
When I execute this in Prog1,
Process.Start("subfolder/Prog2.exe")
Prog2 runs.
But...When I execute this in Prog2,
Dim sw as new streamwriter("1.txt")
sw.write("something")
sw.close
1.txt is created in folder1, and not subfolder.
I can do a easy workaround by passing the full file path when creating the streamwriter, but I just want to know if it's a bug or what.

EDIT: I am able to pass in the string perfectly when using Visual Studio 2005. But when using VS 2003 and a loiwer .net framework it will not let me, unless I hard code it in.
Could something be enabled/disabled on one of these instances of VS? Or could this just be an error with the older versions of .net? I think I am using 1.1??(will have to check) in 2003.
I've been looking at accessing shared folders, read and write, via the network without being prompted by the OS for the username and password.
On this forum, and googling, I can find many things about accessing network shares, but none using code which also passes the username and password required.
What I'm basically looking for is to not have to map a drive on the users computer. Then using code, write or read files from a network share and at the same time pass the username / password required for that network share.
I have Text File of say 200 lines. In that, some headings with special tagging,are present.
