How To Pass Parameter To EXE File
Oct 7, 2010
I 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 have various shape objects, and I want each unique shape to implement a saveToDB method that simply calls a DB object that implements a Save method with an object as its input paramter. This DB.Save method will be a long case function that implements the proper SQL commands based on the type of attributes possessed by the input parameter object.how do I implement the SaveToDB method in my Shape class? Is it something like this:
Function Shape.SaveToDB
DB.Save(Me)
End Function
The goal here is to let each shape save itself without it knowing anything about database operations; I want to isolate db-specific information in my intermediary DB object, so the DB object will have to figure out what type of object wants to be saved into the SQL database and then execute whatever SQL instructions are needed. And then if I override the SaveToDB method in each shape subclass, I can avoid the case statement entirely, replacing it with a series of unique methods such as db.SaveCircle (ob), db.SaveSquare (ob), etc., sincle the caller already knows what it is.

Is it possible to pass a DataRow as a parameter to a sub?The following example will (hopefully) make clear what I want to do.
Code:
myDataAdapter.Fill(myDataSet)
For Each myDataRow In myDataSet.Tables.Item(0).Rows
MySub(myDataRow)
Next
And the sub:
Code:
Private Sub MySub(ByVal drData As DataRow)
End Sub
I get an error at design time: Error 2 Expression does not produce a value.

I am trying to load a combo box based on a selection of data from another combo box. I am not sure how I would pass the value to the object. My thought is I am loading all the table data onto my object and then I would run the query on the object. However I am at loss as to how I would go about doing that.
Private Sub cboOrder_SelectedIndexChanged(ByVal sender As System.Object, ByVal e AsSystem.EventArgs) Handles cboOrder.SelectedIndexChanged

how to use a button to pass a SQL parameter "ContactID" to the next page to allow the SQL to execute the Select Query. From what I've found here is what the code behind for the button looks like.
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim ContactID As String
ContactID = Request.QueryString("id")

The reason why I need to do this is because I have a sequence of two lines of code that is littered all over my program, where I dynamically remove the handler to an event, then set the handler again. I'm doing this for several different events and event handlers, so I've decided to write a function that does this. [code]...

I currently have a page that is populated using a filter, which passes the parameters of the filter via URL.
I'd like to catch those parameters and give the user the opportunity to return to the page with the same filter applied to their view. Essentially, it's a back button. AKA: pass the parameters back into the URL so it repopulates the page.

I'm new to VB.Net. I'm using a library call setInstance(ByVal instance As UInteger) in my VB.Net code. The parameter I need to pass is an Integer. Is there anything I need to do to convert the integer parameter to an unsigned integer? The number is garunteed to be positive and less than 10.

Can I pass a form as a parameter in a sub like public Sub GetData(Byval Frm as form) and access its controls?I have few forms (you can say: FrmAccounting, FrmEngineering, FrmIT) with almost the same controls in each of them (txtEmployeeID, txtEmployeeName, optMale, optFemale etc), where no two forms are open at same time, and each of those forms have a Button which opens a new Form (you can say FrmCollectData) now I want to fetch data in FrmCollectData depending on which form it was opened from.. like if user was on FrmEngineering and it clicks button to open FrmCollectData.. form collectData fetches data from FrmEngineering Controls and if user was on FrmAccounting and it opens FrmCollectData, form Collectdata fetches data from FrmAccounting..
earlier, in VB6.. In one of the Sub written in frmCollectData I checked which form is opened by setting flags in each of forms (frmEngineering, frmAccounting etc) and then I passed the same form in a sub which writes data in frmCollectData controls.. but am not able to do the same in VB.NET.

Just asking for personal preferences, pros,cons on the following situation. I have a class(classA) that has some shared members in it. I have a procedure in a form that needs to execute a function in a separate class(classB). This function requires some of the shared member values from classA. I can either pass these values as parameters from the form to classB, or in classB I can just access them directly by referencing classA. As a general rule I've tended to try to use parameters to pass all the information a function needs but it starts to seem a little unwieldly when passing several parameters to multiple procedures.

I need to write a long-running process with a While/End While loop.
To avoid freezing the UI, I added a BackgroundWorker object on the form.
Next, I needed to update the UI, but found that the thread cannot do this. Instead, the thread must call ReportProgress() to trigger the ProgressChanged() event.
However, I need to pass the text from the exception (ex.Message) to the event, but didn't find an example on how to do this. I need that text message to update the form's title bar.
Here's the code:
Private Sub BackgroundWorker1_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork
While (True)

When adding to a NameValueCollection you normally would do this:
nvc.Add("SOME LITERAL STRING", "MY VALUE")
but if you dont know the first parameter until you read it in from a file then you would want this:
nvc.Add(myVar, "MY VALUE")
this does not work! The NameValueCollection parameters SAY they want a string, but they really don't, they want a "Literal" sting.
So, the question is: How do I pass a variable string to the first parameter?

After reading this post i realized that i cannot pass an anonymous type as a parameter to a function. So what other options do i have?
Perhaps, passing a Query.ToList as parameter would help, or am i re-inventing the wheel?
Update: I have the following query, which i would like to pass to a function:
Sub Test
Dim Query = (From c In DB Select New With { .ElementName = c.Name })
DoSomething(Query)

I have a SqlDataReader and need to read a varbinary(max) column from it using the SqlDataReader.GetBytes() method. This method populates a byte array and therefore needs to know what length of data to read.This is where I get confused.. Clearly I want to read all the data that has been returned from the database in this row/column so what 'length' parameter should I pass?As far as I can see, the SqlDataReader doesn't provide any methods to discover what length of data is available, therefore this method seems fairly awkward to me.I'm tempted to just pass int.MaxValue here and forget about the issue but something about this doesn't sit right with me.
I am aware that I can instead call
byte[] value = (byte[])dataReader["columnName"];
.. and this seems to completely take care of the length issue internally. However I am working with a set of complicated code generation templates that have been built around the SqlDataReader.GetXXXX() methods. So I am tied into using GetBytes and need to understand its proper usage.

I'm currently working on being able to import a DLL written in Fortran into Visual Basic. I've got all the basics down, so now I'm trying to take it a step further. The title basically says it all, but I'll explain what it is I'm trying to do anyways.
For kicks and giggles, let's just assume I want to pass an object that has three double values in it, possibly representing a point in space in three dimensions. In my Fortran method, I want to take that object, print out the x value, then change the x value to 7.5. Here's my Fortran code that does just that.[code]...
