I was asked to build a winform exe that receives arguments from a web service and decide in which mode the application should start.what is the best way to design and build the application?The application needs to receive 3 arguments.
User name. - stringApplication mode - Boolean (user read write privileges)List on string.
Where do I receive this arguments in the new method ?
I've constructed a custom System.Windows.Forms.Form that requires arguments to New. I want to use one of these as the MainForm in a Windows Forms Application. How do I get the Application Framework to pass those arguments as needed?
View 1 RepliesI have created a dialog as a winform and am calling that winform like this:
Dim dlgEditChangeOrder As New dgEditChangeOrder
Dim dlgResult As DialogResult
dlgResult = dlgEditChangeOrder.ShowDialog
pretty simple. I want to be able to set the visiblility of a control on the win form when the win form is called. I would like to do this as a constructor so I could write the following. Dim dlgEditChangeOrder As New dgEditChangeOrder(visibleIsTrue)
Can someone give me the contructor code to make this happen? The reason I am concerned is I dunno if its legal to do this inside a winform since the winform is loaded bby the precreated IntializeComponent() function
I have a base class, "B", which has two constructors, one with no paremeters and the other that accepts one param, an integer. I have a subclass, "S", which inherits from "B" and does not define any constructors in it. I create an instance of S, attempting to pass to the constructor an integer.
I get the error: Error 1 Too many arguments to 'Public Sub New()"
This surprises me because I thought that if a constructor is not defined in the subclass, S, that the base class constructor method, specifically, the one with the single integer param would be invoked w/o an error. why I am getting this error? Are constructors a special case?
I have a userControl11 (either in winform or wpf) which has a ValueChanged custom event. If I put it in client form and in form_load set its value to 100, it will trigger the ValueChanged event. But if I set this value inside the constructor of UserControl1 the custom event won't trigger. How can I force it to do so ?whatever the technical reason, functionally it does make sense. If the object is initializing its value from some sources unknown to the client form and the client form has a textbox bound to this usercontrol value, it is sure convenient that it could refresh its textbox at any time including when the form loads just using one single event handler. Without this the client form has to create another initializer for this bound textbox at form load.

I have an abstract class which requires a delegate to function. I pass the delegate into the constructor. Now that I have a non default constructor I need to call the abstract class's constructors from the concrete class which means that I need to use MyBase.New(...). I have included a quick example below.
Public MustInherit Class BaseClass
Public Delegate Sub WorkMethod()
Private _Work As WorkMethod
[code]....
I have tried to do this but I keep getting the following error: "Implicit reference to object under construction is not valid when calling another constructor".Can I not do what I am trying to do above? I initially had the delegate setup in its own setter method. But then I am creating a deceptive API because it does require a point to a method to work properly.
I trying create Application for the BMP Constructor, I already write the code in C# but I can't translate it into VB.NET, because its require pointer, and as far as i know, there are no pointer function in vb.net @@ so how I can translate this:
FileStream fs = new FileStream(OJSPathBox.Text, FileMode.Open);
BinaryReader rdr = new BinaryReader(fs);
int width = 555; // its just for example
int height = 555; //its just for example
[code]....
ptr declaration is using Pointer and I throught, there are no unsafe in vb.net, how I can translate to vb.net language?
what's the rationale behind this limitation: Constructor call is valid only as the first statement in an instance constructor i want to pass an argument to my constructor which validates this argument and calls mybase.new according to this argument but it doesn't let me
example:
Public Class prob
Inherits System.ApplicationException
Public Sub New(ByVal problem As String, ByRef inner_exception As Exception)

I would like to make a vb console application that takes parameters. Particularly, I would like it to save each specifc parameter as string.

View 1 RepliesI am a newbie using VB.net in VS 2008. I took over a vb.net winform application that has a binding navigator in it. The users wanted to add 2 new fields to the form. I added the new fields to the SQL Server 2005 database. I refreshed the Data Source tab in the project. It recognizes the 2 new fields.
I dragged them onto the form. When I go to add a record through the application, it does NOT save these 2 new fields. I check the properties for these 2 new fields under "Data Bindings" and it shows under the "Text" property the correct Binding Source and column name. I need to store these 2 new fields to the table.
I am currently developing a WPF application that will utilize existing WinForm dialogs. I'm experiencing a long lag between the time I call ShowDialog() on a WinForm to the time it is displayed.Even when reusing WinForm dialog objects the lag time is nearly as bad on the second hit. Meaning that the problem isn't in the constructor. have a work around to increase speed or know why the speed is so slow?

I would like to make the Tab movement can also pressing the "Enter" Key. I have google and found the code which possible to used. But I found its not running fine with me. When I press "Enter" key,it runs fine for the tab movement. But if I put something into my textbox,it only allowed me to put 1 character and it will move next. Because the Textbox 2 can able to put in any kind of numbers. But after add in the code that allowed "Enter" key move the Tabindex,it will move to the next tab index after I lick 1 character.

View 2 RepliesIs it possible to restart a VB.NET application, but with different command line arguments than it originally had? Here is the challenge. I want to write a single instance application. If the second instance has the same CL args as the first, then the built-in behavior is fine (second instance never opens, e.BringToForeground=True brings 1st instance to foreground, everything is great). But if the second instance has different CL args, then I would like the first instance to close and the second instance to start. However, once you mark a VB.NET app as "single instance only", it appears that you can never get the second instance. I think: OK, fine, I can just restart my first instance from the StartupNextInstance event. But how do I use the new command line arguments from the second instance? The Restart() method does not take CL args that I can see.
View 5 RepliesI have an application that has file extensions associated with it. The application has been deployed using ClickOnce. I have checked the associations table to confirm the entry is there and the association is to the 'ClickOnce Application Deployment Support Library'. When the application is triggered using a file with my extension, it does not pass the filename / directory in the CommandLine Arguments, instead you get the executable path of the application.
Which is under ..LocalSettingsApp"Random Strings"MyApp.exe
I have checked the Registry entry to confirm what the extension is set to open with and the application is dfshim.dll. Is there a way to overcome this, or is this just another limitation of ClickOnce deployment?

I'm looking for a simple way to split the path to the application and the optional argument.Sometimes the string contains quotes around the path (1&2) and sometimes, even when the path contains spaces, the string does not contain quotes(3). And sometimes the string does not contain spaces in the path (4&5&6), but a space is used before the argument(4). And (6) is a executable without a path. I have to use the environmentvariables the find the fullpath of the executable. This string (6) can also have arguments.Is there a standard function available to do this split?
Note:I have a regex pattern to handle (1,2,4,5,6), but is doesn't work for (3), because of the spaces in the path."[ ]+(?=(?:[^""]*""[^""]*"")*(?![^""]*""))"I cannot control the strings. Some of them come from user input and some of them come from the registry.
