.net - Pieces Required For A Usable MVVM Framework?
Sep 17, 2010
As my company migrates towards the .NET framework from VB6, it looks like we are going in the direction of WPF (my boss is in love with the Office-style Ribbon control). I've been working to mock one of our VB6 applications in WPF and decided to experiment with MVVM at the same time. I'm being discouraged from using an existing MVVM framework, so I guess I need to write my own. The biggest concern right now seems to be a method for registering and managing all my views from a central spot - a manager class - but I'm not exactly sure how to implement this.

I wrote very simple code to send emails. I wish that end users who do not have .NetFramework installed, could also install this application without installing Net Framework.

How do I tell what version of the dotnet framework is required by my application?I am using Visual Studio 2008.I have these installed on my machine:
.NET FW 2.0 SP 2
.NET FW 3.0 SP 2
.NET FW 3.5 SP 1
Are the service pack 2 updates inclusive of service pack 1? I don't think I need .Net 2.0 - do I need 3.0 if I also have 3.5 ? Do I look somewhere inside Visual Studio, or at my references?

I'm writing a tool the retrieves data from an Oracle database. The majority of the fields are VARCHAR2, but there's one particular field I want to retrieve that is a CLOB. I'm trying to convert the text in this CLOB to a string that I can then run a regex against it to isolate a certain bit of information and then display that information in the program's console. Unfortunately, I can't seem to figure out how to convert this CLOB into a usable string. I've tried a lot of different things, but what I've got at the moment is:

Okay, so, for school i have a project i need to completely program by the end of next semester. My graduation project. And it needs to be a full-blown piece of software that would be theoreticly usable for a person or company.assignment was simple:make an application, usable by a person or company, that uses databases and VB.NET
so i started brainstorming and i came up with the following:a client-server application where the server runs on the company's mainframe and it's employees (seeing as it would be an IT company or another company that would use a lot of computer files) can upload to, and download files from, where each file would have a description and additional information (extension, date,emplyees would also be able to exchange private messages so that collegues of the uploader can be notifies that the file they would need is uploaded.
in addition to that there would be an administrator (or multiple) that can overview all PM's (make sure there's no abuse of the system) and administrate the files (delete/edit/...)So really, i have no idea where to begin building this application, so i would think that if i get the interface done, i atleast have an overview of what and how i would need to code.
note: wow now i think about it this seriously sounds more like a website than an application... but still it sounds like a good idea to me and has to be done or else i would not graduate

I need to know to limit the number of times a radio button can be used. Maybe the number of times the radio button has been used can be stored in an XML file, and when the user wants to reset the counter all they would have to do it delete this file. I really don't know, that's why I'm asking you. But,the program will append a string every time a button is clicked with a radio button selected, I just need to know how to, for instance only allow RadioButton2 to be used in this manner say... 15 times.

Correct the problems with this function, and then extend it so that it also returns a usable array of pointers to some structures.
The extended version of this function should: Maintain the same "char *" return type which returns a pointer to a usable, for storing a C string, memory buffer.
In addition, also return a usable array of pointers to structures. This array of pointers is of variable and random length, which must be obtained using GetNumberOfSomeSeqsToGenerate(), which is called, ONLY, from within this new extended version of the function.
The type of these structures and the function that should be used to get these structures are defined as follows:
typedef struct {
char* name; /* '\0'-terminated C string */
int number;
} SomeSeq;

I'm having a bit of trouble learning the uses of partial classes. I know they are used to split a class into several pieces for convenience but I don't understand how to put all of this into play. I'll show you what I mean here:
Lets say I have an interface named "ICar":
.NET
Public Interface ICar
Sub TurnOn()
[Code]....
OK, now that I have all of that, how do I put it to simple use in my partial class "OffRoader"? (You can add a "console.writeline" event to the methods if you want, in order to show me the uses of these partial classes.)

I am working on a project and the code for FORMS1.vb has become quite large, 20K lines.How can I break this down into more managable pieces. I have tried Modules but I get multiple reference errorsd when I move like all of the reporting code to a module. The report code has nothing to do with the forms other than being able to call that code from an object on the form.

I'm wondering if someone can point me towards a good article/tutorial explaining how to use the MVVM pattern in an WPF Application that uses WCF web services. My WPF client calls a service reference to get data objects that contain data from the database but from everything I've seen and read so far about MVVM I am still not clear on how to use MVVM to work with the data objects I am retrieving from the WCF services.

i am trying to implement a very simple program, that simply copies some text from one window in to an appropriate text box field in the other window. I need to copy and paste about 50 pieces of information from one window in to another.I suppose i can load the entire SOURCE window's text in to a text box control, and then i want to use sendkeys to populate appropriate fields in the other DESTINATION window that i want to populate with this information.My guess is that i will need some kind of windows api (Win XP) to get a handle on the appropriate text boxes in the destination window (or tab through it or something)

I was wondering what the best approach is for sharing a menu across all wpf windows/views. My Application doesnt really fit the navigation model, so will probably use a Ribbon control. I am leaning towards creating a user control for the menu and dropping it on each view, but have also seen Josh Smith's msdn article, where he loads user controls.

I seem to have a huge issue right now trying to grab different pieces of a string to place them in a different order in a list. Unfortunately i can't just find the placeholders for the strings and extract the data that way so i was using indexOf to find commas in the string provided. the problem i'm having is that i can assign the first comma and extract 0 - "," but i'm stuck on how to progress the indexof so it will move through the string submitting everything between the comma's.
