Hi,
I'm not new to programming, but fairly new to .NET (I'm an old timer). I've been teaching myself C# since I am an old C/Unix programmer and thought it was a better alternative to VB.
I've been scouting around for the last month to invest in a RAD tool, and there are some application generators that I have reviewed. So far I've checked out DeKlarit, DevForce, and IronSpeed. The latter is nice but I don't necessarily want to do web apps only. I also own Infragistics controls, so it must be compatible with them.
There is quite a price range in these three above, and they all seem to have their pluses and minuses, but I feel it would be worth the investment to get a tool to give me a jump start on some larger scale applications without the huge investment of time in developing my own home grown application framework. Plus at my skill level, my first cut wouldn't be very good anyway.
I would appreciate any comments from individuals with experience with the above products, what you think of them, what the strengths and weaknesses, and if you recommend it (please specify what version you own, i.e. basic, professional, enterprise). I would also like to hear about others that I haven't yet reviewed that you found to be preferable.
Thank you in advance!
John L. Miller

I remember anticipating the arrival of FrontPage. When it finally arrived I jumped on it and WSIWYGed a page up pronto. Then I had to manually modify the code to apply a feature the designer didn't support. I opened the code for the first time, puked, closed FrontPage and never used it again.
IMHO Visual Studio is the premier development environment for doing Windows development. The small amount of code generators built into VS works for me. To generate the remainder of the code I invoke my brain and use the keyboard to generate the results.

I understand what you are talking about, but my situation may be different than yours.
I spent the last 15 years primarily as a Visual FoxPro independent developer, and I learned it from scratch, in my spare time. It took me two years. I developed into one the premier VFP developers in my region. Well, the writing is on the wall and Fox is dying a rather quick death now.
Back in the early days of my FoxPro experience, I bought a framework and just like you, found it full of fluff. But it did help me develop my own base classes that handled database issue, especially multi-user concerns. This was worth the price of admission alone. That set of base classes evolved over time but was used in nearly every application I wrote since then.
As as independent, I do not enjoy an employer sponsored educational process. I must get quickly productive. At 46, I do not have the energy level to moonlight after hours every day after my normal 60 hour week.
What I am hoping for is to find the best code generator for me, whatever it may be, then lift the hood and see what makes it tick. I'm a very visual learner and would quickly catch on and find ways to improve upon it. However, to start from scratch and figure out things like how to handle record contention when there are tools out there to produce a working copy for me, this is not a desirable route for me.
Thank you.

Ok well like I said I have no experience to tell you about but I have seen members on this site speaking well of Iron Speed. Good luck, oh and that writing about VFP was on the wall like 10 years ago.

LOL, yeah, I know. There was a mass exodus out of VFP when .Net was released leaving a giant vacuum of unsupported clients and abandoned applications. I've made tons of money since then filling this need and even to this day am extremely busy, but I got back on the leading edge with my Sharepoint 2007 experience. Now it's time to fill in everything in between and I should be in decent shape.
Thanks for your replies. Good luck.

Hello
I'm trying to pass a pointer array to a dll and get back and array of char **
I'm in the middle of the way because I already can get the first string pointed by my array
Concept : I pass an Id and a char ** to a DLL , the dll allocates his buffer and an internal char *array then assign that char * array to the passed pointer
What I do in Csharp
[DllImport("bcta.Dll")]<br />
static public extern int bctaGetName(IntPtr hBcta, UInt32 nAttID, ref IntPtr [] StrPtr);<br />
<br />
static public int TestName()<br />
{<br />
IntPtr hBcta = (IntPtr)0;<br />
UInt32 attrId = 1039;<br />
int count;<br />
IntPtr[] StrPtr = new IntPtr[8];<br />
<br />
bctaOpen(ref hBcta);<br />
attrId = 8967209;<br />
count = bctaGetName(hBcta, attrId, ref StrPtr);<br />
string aa = Marshal.PtrToStringAnsi(StrPtr[0]);<br />
bctaClose(hBcta);<br />
return 0;<br />
}
This is working fine for the FIRST string but my inPtr array is modfified by the DLL and it only contains 1 element at return however my count is 3
I miss something in the declaration but I can't figure out what ?

I strongly recommend wrapping native C/C++ DLLs in a mixed mode assembly using C++/CLI that then publishes one or more managed classes as an interface to pure managed languages. In this approach you can use native C/C++ to interface to the existing DLL simplifying the management of native types like pointers to pointers etc.

???? ! 
I'm sorry but I do not understand what do you my nor I can't see any solution to my current problem
I'm already using different function of that dll without any problem.
The problem here is how to declare an IntPtr to be modified by the DLL function
Example In C
char *ptr;
void function (char **ptr)
{
*ptr=calloc(10,sizeof(int);
}

Thank you
But your comments are not very usefull
This is how I do it in C
char **xptr;
bctaGetName (hBcta, id, &xptr);
// the ddl function will assign his own buffer to the adress so I can now read xptr[0],[1] etc...
// The question is HOW to do the same in Csharp (I can not declare a pointer to IntPtr) and if I give the ref of an IntPtr array I need to assign the Array before the call and that array will be lost into the call so only the first element will be usable !
|

I got it !!
Using pointer and unsafe !
static public unsafe extern int bctaGetName(IntPtr hBcta, UInt32 nAttID, out IntPtr** StrPtr);
unsafe static public int TestName()
{
char ch = (char)1;
IntPtr hBcta = (IntPtr)0;
UInt32 attrId = 1039;
int status;
IntPtr** StrPtr;
Routing.bctaOpen(ref hBcta, Environ.RoutingDataPath, ch);
attrId = 8967209;
status = bctaGetName(hBcta, attrId,out StrPtr);
string aa = Marshal.PtrToStringAnsi((IntPtr)StrPtr[0]);
Routing.bctaClose(hBcta);
return 0;
}

I need that to.
Please send me the code, its urgent..
|

As you are posting here, and don't ask any specific question about the implementation, I assume that you just don't understand the assignment?
Don't you have any more information at all other than the one that you have given in your question?
If your google is broken, here's some basic information about the three address code concept:

Despite everything, the person most likely to be fooling you next is yourself.

For some reason DateTime.DaysInMonth(2008, 4) returns 31, yet DateTime.Parse("2008-04-31") yields in a FormatException.. am i missing something here? or is this some sort of bug.

Yeah, how to create a subject line that is meaningful and descriptive.
only two letters away from being an asset
|
|

|

Running the line of code you just mentioned returned 30
<br />
MessageBox.Show(DateTime.DaysInMonth(2008, 4).ToString());<br />
<code><br />
<br />
Sorry not much help there but I just thought id give you the result of my test. Very strange that it is returning 31 - it doesnt seem possible.

Yeah, I assumed he fat fingered the date and meant March, but if you're talking about April - yeah...that's a problem ;D
|
|
|
|
|
Aside from the bad subject line, I'd say your problem is that its parsing your date assuming a YYYY-DD-MM format.

Yes what Mark said and the fact that those two methods you posted have nothing to do with each other so your post is like saying, for some reason you can eat potatoes yet jumping off a building will hurt you.

led mike,
How tall is this building everyones jumping off?, I hope its not too big..

I want a method to return different data types or classes. For example, sometimes I want the method to return an integer and sometimes I want it to return a string. I can do this by letting the method return an object and then the calling function has to cast the object into the appropriate type. Can I somehow make the calling function automatically find out which class or types it belongs to and "cast itself" into the appropriate type? Basically, this is what I want to do:
object myObject = myMethod(); // Can return an int or a string, casted into an object
MessageBox.Show("" + (myObject.GetType()) myObject); // Should work for both int:s and string:s
I want the expression
(myObject.GetType())
to be interpreted as a cast. How can I accomplish what I want?
Note: I've simplied the problem in order to make it easy to understand. Using ToString won't solve my real problem.

That kinda defeats the point of a strongly typed language. why would you ever want to do that?
(As far as I'm aware a dynamic cast like that isn't possible. you wouldn't know at compile time what type of object it was, so all it could be assigned to would be an Object type, so you'd instantly lose the cast Feel free to correct me if anybody knows better)
You'll probably find your problem is better solved by redesigning the class hierarchy your using, or using Generics instead.
Post a bit more detail so I can try to understand why you need to do this.
