I have a .NET application that was written in C# and VB.NET using WinForms. We want to slowly migrate this to something new, in many iterations. The new code will be entirely C# and WPF. We would like to utilize Prism.
As far as I know, we can't integrate the old WinForm app in Prism.
I am considering making my old app show the new app in certain instances. For example, when you press a tab in the old app, the new app opens on top of the old app, with the same tabs. Over time, only the new app would be necessary.
what WPF based apps are?Is it an application that runs under Silverlight? If so, how?I know; Windows Forms based apps,console apps,DLL _ Class Library Projectsand I've had an introduction to ASP.Net.What I mostly want to know is, if WPF apps are for Silverlight then do they also run in a server based fashion like anASP.NET website would when you create ASP.Net webpages?Is it a way of creating what looks like a FORMS BASED application but it runs in a browser instead or what?Please enlighten me a bit further as I have no idea what WPF is all about.
how to switch between VB.NET and C#. I need this information because I have a project that needs application building and the programming language is C#.I found a good sample program on the Internet which uses an SDK called Ozeki SIP SDK.

I am using Visual Studio 2010. I have a Splash Screen which starts first (Everything is running smoothly there). Then it Opens Dialog1. My user is required to check 5 boxes (2,3,4,5,6) (1 has been deleted). I used this Code :
If CheckBox2.Checked And CheckBox3.Checked And
[code].....
I've been experimenting for an 1 hour. The code didn't show errors. I tested it and it didn't work. Then I found out that I was working on Dialog 2 in Dialog 1 code. So I tried another thing and that didn't work because I can't put Dialog2 code in Dialog1 code.
I have two machines, on the first of which I have developed my application to a point of satisfactory stability. Now I want to move everything to my second machine.Both computers have the same level of XP and NET Framework code, and both have Visual Studio 2010 at the same level.I copied my application's project folder onto the second machine, but the second machine's VS 10 can't load the project because it can't find a couple of Interop files (e.g., AxMSComCtl2). All of files are present in the project folder and also in its.bin subfolder. The only observable difference between the two machines is the presence, on the first machine, of some Assemblies stored under my user name there. Copying the Assemblies to the second machine didn't help (I hadn't thought it would).Is my application permanently "imprinted" on my first computer, or is there a simple way of resusitating its clone?
I always get an exception when I try to switch between different forms in my program. Here is the exception message:
Control.Invoke must be used to interact with controls created on a separate thread
I have attached the forms to very nice variables and this problem occurs when I try to use command like MyForm.Show().
It does not happen when the forms are not attached to variables, but then I have collosal problems with refreshing the textboxes and stuff.
edit;
I have 4 different forms. When I load the main module and main form, in the Sub (...) Handles MyBase.Load I execute the following code:
In module:
Public StartupForm As frmStartup Public RegularForm As frmRegularUse Public LoginForm As frmLogin
[Code]....
This is the aproach I worked out to get the full control over refreshing the forms. It is a program for Motorola Scanner with Windows CE. Now, for example, when I enter the correct password in LoginForm, I want to switch to the RegularForm. When I try to use RegularForm.Show() or RegularForm.ShowDialog or RegularForm.BringToFront(), I get an exception. When I try to call the form with the frmRegularUse.Show() I can call the form, but it is being created in a different thread, I believe, so I loose control over it (when I try to put something from the keyboard, there is no response).

VB.NET is good for me, because it is simple and its not complicated and you don't need to be so strict with syntax. I want to switch to C# but I just don't feel up to it because of the syntax and C# being so strict. What are some good reasons to switch to C# and what will make the transition easier?
I am using an Application server for calling Oracle Reports and I have a URL to call the report. When the report is called the server converts it into PDF but when report contains large data it takes a lot of time to load. I want to do in asp.net that when I call the report url it opens the PDF file and copies it into the root of my web folder. The next time when I call the URL it opens the PDF file and creates a new PDF on backend for next call. I have made this function to download file
Basically, i am trying to determin if an application made for 1.x will run on a computer with just one copy of the .NET framework installed which is a higher version than what i am targetting, ie: it only has one copy of .NET 2.0, or 3.0, or 3.5 or 4.0 - has one copy of either of these and thats it, the hypothetical computer would not have 1.0 or 1.1 installed.
Usually when you right click on an application, and then click on properties, you can find the applications exe name. Such as, explorer.exe, mspaint.exe, and much much more. But I can't find the exe name of any of my apps.
If I control both applications, what is the best way to communicate between 2 exe's written in VB.Net. For example, I want to drop an XML file from one app, and pick it up with the other, but I do not want poll for the file. I've heard of named pipes, but I found it was complicated. What's the most effecient way to do this?
Private Sub startMySQLConsole() Dim parameterString As String parameterString = ""
[code]....
For some reason, it partially exists the program. The first letter of the line is starred (MySQL wants me to enter a password).I want to use get to mysql via the my app, which launches mysql.
I'm developing a media player app and upon looking at it for a week now, it seems really bland. I would really like to add some animations for it (besides just moving forms with x,y locations) but have no idea where to start.
Are more complex apps/designs/animations better suited for a language like c#/c++? I've never done animations before (except simple form moving) and I think now would be a great time to get some opinions!
You could probably say this would linger more so on 3d images and 3d animations
I've heard a lot about Mono but I have no idea what exactly it is or how to use it. All I know is it's aimed at making .NET apps cross platform. Could someone tell me or point me to some tutorials explaining how to port my vb code to run on other operating systems? Maybe shed some light on all of this?
I have downloaded SP1 and installed it,I have an applciation with 10 form and numerous classes and dialogs. When I right click a form in the soultion Explorer window and choose view Designer VS hangs for anything upto 10 mins. Is there anything that I can disable/ enable to stop this hapening. The only Language that I will be developing in is vb.net.
I have been programming for alot of time. Generally i program in some languages like PHP, ASP.net, Java, JavaScript and others. In all languages i have to use alot of if else statments . Like if value= 10 then ... if i review my code then i find alot of if conditions. So i would like to minimise them but how not sure. one point was using classes somewhat minimised but still they are more... like task, cat, sec and type:
In my program I want to have two different 'modes', each has its own form. My main form in the program is 'Normal Mode', but there is also a mode called 'Basic Mode' which has a smaller form. How can I switch between the two forms (using buttons) by closing the other without my program closing on me?
How can I monitor how many times a switch open and close? I am planning to add a label13 to my form and use the LPT port so every time the switch goes high (1) it will add 1 to my label13.text. The Printer Adaptor address in the target PC is 0x378. using pin 10 (ACK) or pin 2 (D0).
There is a machine in which .NET v1.1.4322 was installed and also .NET v2.0.50727/v3.0/v3.g were installed.Can we switch these runtime version for each applications like Java applications?Or we can not switch runtime and we can just use only the installed latest version in the machine?
I want to have a DataGridView that has two columns.The first column will always be of type DataGridViewComboBoxColumn. Based on the selection in that column, I'd like to be able to change the corresponding cell in the second column to either a DataGridViewComboBoxCell or a DataGridViewTextBoxCell.I'm thinking I just need to make the second column of type DataGridViewColumn, but don't understand the mechanics of how to change the cell type on the fly.I'm working with VB.NET in Visual Studio 2005.
Update: One way around it, I suppose, is to make the second column as a DataGridViewComboBoxColumn, and change the attributes of the cell so that it either behaves like a drop-down list, or as an (editable) drop-down with no elements. The latter looks enough like a text box that I could live with it, and it wouldn't involve changing the type of the cell.
Is there a way to change the language of an ASP.NET project from Visual Basic to C# easily? I would even be willing to re-write the code as it's still fairly simple at this point.
