Pass Parameters To A Subroutine From A WPF Button?
Jul 26, 2010
I have a VB.net WPF application that creates a list from a databind. For each row in the databind, it generates a textblock that displays the information from different fields in the databind. It also generates a button which I would like to run a subroutine when clicked.
When I click the button, I want it to be able to get the information from the databind on the column the button is clicked, and to pass it to the subroutine so the code-behind can use that information.
I have two subroutines that consists of two datasets. I am not sure how to pass some data in first dataset named dsGoodStudent to second dataset named dsBestClass.
Private Sub Classification() Dim SqlSelect As String SqlSelect = "Select Name, Age, grade from tblStudent where grade = 'A'"
I have hundreds of variables and need to see if they are duplicated. Is there a simple function I can use to achieve this rather than repeating the code for each? The variables have different types. Can you pass a variable name into a subroutine?
1)Send a request to an external hardware by SerialPort1.write.
2)Receive this information in SerialPort1_DataReceived.
3)Set this information (integer from 0 to 31) on UserInterface (like cell phone signal level....)
How to pass level information to this graphical subroutine without receive cross - thread error?

If I want to use a FolderItem verb like 'Copy to folder', then I have to somehow supply the name of the folder to which I want the object copied. How is this done. I dont understand how msdn can be so minimal on examples.
For example if I have a function call like below Function callingMe() Exit Function
And my Function call is like below SomeObj.callingMe('1','2','3','4','5') // Variable number of arguments Inside callingMe() function, I want to know arguments passed i.e 1,2,3,4,5 and the Object i.e SomeObj in above case.
I've created an exe that is a ticket management system for in-house debugging, etc... It uses the same database that is accessible via MSAccess. In order to create a seamless work environment, one of the supervisors wants employees to be able to see data from the tables the exe uses without actually opening the exe and looking up the record. That's no problem since it's all the same db, but they also want to be able to open that ticket with the click of a button...instead of opening the exe and doing the search themselves, they want to just *click* and have the appropriate ticket open in front of them. I have no clue where to even start to do this....
I have two charts one of residents and another of payments, I want to unite them by a parameter that the user enters to show the result. I have written this
SELECT CasaNum, FirstName, LastName FROM residents WHERE (LastName LIKE @LastName) but when writing this code in the button me the error Me.ResidentesTableAdapter.Fill(Me.Por_apellido_DataSet.residentes, LastNameTextBox.Text)
I've been trying to pass two parameters to my report using code the two parameters are DateTime type, my problem is crystal report viewer is still asking for the first parameter only and it accepts the second one?! in my report i've used two parameters ?firstDate and ?secondDate as dateTime parameters and used them in selctionformula where the date is between the two paramters.[code]...
I have a bunch of methods that do some formatting on data that is contained in a structure. I'm passing the structure to the methods as a parameter. The problem is that the same structure is returned from 2 different webservices depending on the program flow (I did not create these services and cannot change them). So at one point I would be passing WebService1.Service.MyStruct and later I might have to pass WebService2.Service2.MyStruct.
Is there a way I can write only one method to handle both type of parameter? The struct is the same and only differs by namespace. I can overload the methods but I was wondering if there was another way to do this with reflection or something along those lines.
Just kind of curious about something: why does VS (vb and C#) default params to pass-by-value?I almost never need or want to pass anything by value. Maybe this is some reflection on the way I code. I would never manipulate a value type param directly; i would just return the new value from a private variable... and I just don't see the need to do the background work all the time to add copies of everything to the stack. Why wouldn't I just about always want to pass-by-ref?
I have a web app which has a listbox of all the available reports for a particular user. I want to open a new page 'ReportViewerPane' when a row is clicked and pass the report name and some parameters through to the reportviewer.aspx I then need to set the ReportViewer controls .reportpath to the correct (passed through) value and set the parameters values (also passed through).
I the moment I have this in the parent page. 'PassParmString' is a textbox on the main form:
function open_win() { var Parms = document.getElementById('<%=PassParmString.ClientID %>');
I'm developing a website with ASP and VB.NET 4. I'm also using the FullCalendar jQuery plugin, but I have a trouble: catching a parameter from querystring to the webmethod in the .asmx. I've tried to refer the querystring property with the Request.QueryString() and it doesn't work.
I am using the LiteralControl to add some HTML in the codebehind. It's working great and I have added a button, when the button is clicked I want to trigger some JQuery and pass some parameters through. A simply onclick should suffice, now code below works when I DO NOT PASS any values through with the onclick. But the second I try to PASS some parameters through with it (second example) it does not work, anyone know why??[code]
we have an old vb6 application (let's call it app-vb6) that basically handles database searches. now i created a new .net application (app-dotnet) that can use the database information to do something else.
what i want to do is to be able to run app-dotnet using information obtained from app-vb6 (which would send something like a command line with a few parameters). but i don't know how to make only one single instance of the app-dotnet to refresh information every time app-vb6 calls it. this link [URL].. seems to have the answer but i could not follow it since it is VC.
This code calls a store procedure that takes input parameters. With this code I'm confused as to how the parameters are passed to the stored procedure. The parameters are first stored into 2 string variables (strCategoryName & strOrderYear). They are then copied/moved to an sql parameter prm.value. But the stored is stored in an sqlcommand (cmd ). I can't understand how the stored procedures knows what the parameter values are.
Private Sub btnWithParameters2_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles btnWithParameters2.Click Dim cnn As SqlClient.SqlConnection = _ New SqlClient.SqlConnection("Data Source=SKYROCKET;" & _ "Initial Catalog=Northwind;Integrated Security=SSPI") [Code] ......
Can we pass parameters to a function using delegates

My issue is to Find exact one Calendar object from a List Of(Calendar) by passing a particular date. I got to know about the predicate but not sure about passing parameter to it.
colorcode is List Of (Calendar) and calendar class has a property called DtmDate with which I want to compare and return the desired object. Dim a As Calendar = colourcode.Find(AddressOf New Calendar.FindByDate)
I got the predicate samples from Google and reached till now. But not sure how to pass my parameter i.e. date to it.
I am calling a XML web service (standard web service project based on .NET 3.5) and trying to pass custom types as parameters. The custom types are defined in my consuming code and the web service references an assembly from the consuming code to get access to the types. The serialization is being handled by .NET.
<WebMethod()> _ Public Function MyMethod() As MyType Dim myValue as new MyType return myValue End Function
In my consuming code I created a web reference to the service and the proxy classes were created. I gave the service the namespace "WebService". Next I try to make a call to the service and assign the result from the call to a variable, something like this:
Dim service As New WebService.ServiceNameSoapClient Dim response As New MyType response = service.MyMethod()
I get an error from the IDE saying that it cannot convert type mynamespace.WebService.MyType to mynamespace.Entities.MyType. It appears to me that although the types are similar they are being treated as different because of the different namespaces, which makes sense of course.
Edit: So from what I am reading I believe this is by design, that is the proxy types are simply different types and cannot be directly associated with the types in the consuming code.
Today, I'm proceeding with my college work, and am having a little trouble. I'm writing a function, but would like to pass custom types through as parameters, for example Function Game(Section as Game_Section) code here End Function I tried using a structure, but it kept giving me errors
I'm looking to pass two or more parameters to a thread in VB 2008.
The following method (modified) works fine without parameters, and my status bar gets updated very cool-y. But I can't seem to make it work with one, two or more parameters.
This is the pseudo code of what I'm thinking should happen when the button is pressed:
Private Sub Btn_Click() Dim evaluator As New Thread(AddressOf Me.testthread(goodList, 1)) evaluator.Start()
Im trying to pass parameters to a stored procedure in SQL but for some reason its storing the parameter(s) in the columns....
My code

[code]....
the addwithvalue all the textbox`s have a value in which i would expect but for some reason when i go to db in SQL it actually shows the @Username,@Account,@Password,@DatCreated not the values im passing in please see the attached image.
I cant seem to find a solution on how to pass parameters to another exe like adding some parameters after path in shortcut, and then launching that shortcut, only I want to do it directly without making shortcuts. So ,how would I pass parameters needed to start another exe (console in my case)?
