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 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 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.
how to use Visual Basic to pass arguments to an application after said application was started. Example, "myapp.exe -d" enables debug mode, I want to be able to start myapp.exe then have a checkbox labeled "Debug mode" in Visual Basic. Upon "Debug Mode" being checked, it passes the argument -d to myapp.exe. Upon it being unchecked, it withdraws that argument from myapp.exe.
View 4 RepliesI have a listView control on one of my form. It contains no of records. Now my question is how to pass a particular record or its reference to another form i.e. I have designed a form which display's the details of a particular record (Searching facility is there in that form.). When user double clicks on the particular recode in the listView, I want to load that record into the 'search form' (i.e. the form which displays the full details of a particular record).
View 2 RepliesI 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?
how to pass value other than from constructor.

View 9 RepliesWhat I want to do is pass a Type to another object's constructor, where the other object creates a new instance of Type. I can create a constructor with a parameter declared as System.Type without problem, but when I try to instantiate it tells me there is no such type.
Public Sub New(targettype As System.Type)
Dim Test As System.Windows.Forms.Form = New targettype

I have to write an application that consists of mainly one main form, but several different things I wanna display. Pretty standard I guess. So there is a menu, some controls, and the main stuff below (ranging form graphs, tables, dropdown boxes, print preview, etc). I would like to use it like one would use frames in html, design an object that is limited to a box or panel that I define. The literature I have does not give me a clear idea of how to do this (yet). The most obvious seem to be the use of MDI, open a predefined form with no borders, maximize it before showing and remove all minimize/maximize options. But that does not work so well. The form inside the MDI parent does not fit the size that is given for it when it is loaded. e.g.
[CODE]:......................
So my main question is: Is MDI the way to go here at all or are there better/easyer ways to achieve this? If MDI is the way to go, how do I sucessfully restrict a child form inside another object, without giving the user any opportunity to resize (i noticed that I have minnimize/maximize/close buttons, even if I disable them on the child forms themselves)
how can I use main form like MDI parent form in window application?
View 1 RepliesI am developing a commercial application that needs to do some environment checking upon start up. I need to check things like the following. 1. Is there a registry entry on this machine that has various keys for paths to SQL Server 2. If it does not I need to create them. 3. Prompt user for the path to the SQL Server 4.Check the SQL Server to see if the database I need exists. 5. Create the DB if not. 6. Populate the DB with the tables I need 7. Create stored procs in the DB 8. Write the registry. I could do all this in the form load of the main form. However is there a better way? Like doing all these checks as part of a splash screen for example.

I have an application which sits on general users machines. What I want to be able to do is for the users to create a new directory through the application that will create a directory on a server that they do not have access to for secutiry reasons. Then the users can create a file within the new folder through the application, again which they do not have access to. The whole idea is to have an application that manages files that are able to be accessed by many users through the application / backend database, and therefore we do not want the user to be able to manipluate the folder / files by mapping to the location. Then if the user wants to work on the file he requests it through the application which then copies it locally to their machine.
The way that I can see this working is by having a service running on the server that has access to create folders and files in this location. The user can then request the creation of a folder / file through the application which then instructs the service to create the folder / file.
Is there anyway that I can pass arguments directly into the service on the server, or would I have to create an entry in a database on the server that the service is monitoring and then performs the request?2a. If I do have to have the service monitoring the database if I make the service check this every second will this slow the server down and will the server guys at a company be OK with this running this quick?I also need to be able to let the user know through my application that the folder / file has been created successfully, therefore what is the best way to do this? Again get the service to write to the database that the request has been completed? If this is the case then my app will have to poll the database continually to check the database that the request has been completed, this could slow the application down?

View 2 RepliesI've been trying implement Constructor method in passing variable between two forms.Just a rough user interface guide - issue Invoice. User would type in all the Customer Name, Document Number. Once he reached Item Details, a Child Form would pop-up for the User to select/search the Invoice's Item; Once selected, the selected item would showed in the primary Form.
What I had tried is, the Constructor method worked perfectly when it is self-contain in a new project, yet to be implement in my application.But when I implemented, there is an error: Reference to a non-shared member requires an object reference.
