I am new to WSSF and am wondering if it would work for solution with VB as the programming language if so how to achieve it. I have seen samples which generates C# code but my project requirement is VB .Net.
View 1 RepliesJust started a new project and was kind of bummed out that instead of creating interface Im forced to spend quite large amount of time creating objects, INSERTs,UPDATEs.. that kind of thing. Mainly because it's booring. Anyway, I was wondering if there are tools in VS2010 for visual basic that would allow someone to generate clases and INSERT, UPDATE, DELETE stored procedures based on database structure OR creat INSERT, UPDATE, DELETE procedures and database structure based on class structure.

View 2 RepliesI am wishing to emulate the auto code generation that happens when you derive from a class, such as Form, and declare the Public Sub New() constructor. When this happens the constructor will auto-generate code like the following:
Public Class MyInheritedForm
Inherits Form
Public Sub New()

View 1 RepliesI have this code that I have found on the net and I run but there is error that says "Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information.". May I know what is the problem?
Here is the code that I get from the net:
CODE:
I am working on a macro style app for work. I need to have multiple text boxes and drop down boxes auto-populate a single text box at the bottom of the app. (see reference image)There will be two buttons, one to copy the generated text to clipboard, and another to clear the form (including drop down menus, or resets them to the blank state).The text boxes will be filled out during a call, and the text that is entered in them needs to be placed in a single text box at the bottom, in a specific order, and with 'filler text' in between. So, for example:[code]John Doe (123456), Has the following issue: Problem with Computer. And, was resolved by: Offered him assistance and corrected John's issue. Caller was satisfied.The red italic text above is text that needs to be 'filled' between the text entry from above. Then, I need to be able to have a button copy the generated field to the clipboard, as well as simultaneousness minimizing the app.And, I need a Clear Form button that clears all the fields, including the drop down menus.

What resources I need to look for, to generate one png image out of three? Since there are sprite generators out there, that do not do what I want, I wanted to try by myself. The user interface should not be the problem, but i have no experience of generating bitmaps, especially those with transparent backgrounds. I will do that in .net. Letīs say I have 6 png files. I want to put them into one image, where there will be two rows of images in it, so 3 in row, 2 in height, 3*2. Every image might have a little different sizes, so i would need to fill up the space with, um, nothing..
View 1 RepliesI'm working with some very large files residing on P2 (Panasonic) cards. Part of the process we employ is to first generate a checksum of the file we are going to copy, then copy the file, then run a checksum on the file to confirm that it copied OK. The problem is, is that files are large (70 GB+) and take a long time to complete. It's an issue since we will eventually be dealing with thousands of these files.
I would like to find a faster way to generate the checksum other than using the System.Security.Cryptography.MD5CryptoServiceProvider I don't care if this means using a specialized hardware card, provided it works and is not to ungodly expensive. I would prefer to have a method of encoding that provided some feedback as to how far the process has gone along so I can display it like I do now.
The application is written in vb.net. I would prefer to be able to use it as component, library, reference within my application, but I'm willing to call an outside application if there is enough improvement in the speed of generating the checksum.
Needless to say, the checksum must be consistent and correct.
in vb.net while entering a new entry i want to assign a record a unique id like in case of numeric i do this way
Dim ItemID As Integer
KAYAReqConn.Open()
SQLCmd = New SqlCommand("SELECT ISNULL(MAX(ItemID),0) AS ItemID from MstItem", ReqConn)
[Code]....
in this case m using itemid as a unique id and the format is 1,2,3... and m finding out the max and assigning to a new record but how to assign if the previous id is of the a00001,a00002,a00003,a00004...so on. how i do i produce a unique id in this case

View 7 RepliesI face problems while transferring objects between layers (mainly the Presentation Layer), as I work with classes having approximately 40 properties.(I don't reference the DAL in the Presentation Layer)So here's what I decided, I am planning to build an App (maybe Visual Studio Addin) which will help noobs like me to build POCO's rapidly.The GUI of the APP would probably be a datagrid with columns for
1) access modifiers
2) property name
3) data type
4) get method (checkbox)
5) set method (checkbox)
Also, the app will have an option to connect to the table and automatically generate a POCO class I would like to generate Strongly typed C# / VB.NET POCO classes for different Scenarios, Like Entity Framework, LLBLgen etc. I am mainly targeting LLBLgen and EntityFramework?I need the following information:
1) Is there such a tool which already exists
2) What are the things that I have to consider (like nullable types etc)
3) The DataTypes generate by ORM's LLBLgen/EF/nHibernate

i just don't like the gap that exists between the .net framework and SQL database. I've explored everything from EF to LINQ to raw sql command strings.Does anyone know a project acting like a generic editor for a database? Meaning adding tables and relationships and constraints at runtime and offering simple field validation based on the information generated by the database schema. I know you can always drag and drop fields from a datatable to a form and a wizard will give you basic navigation over it, but I was wondering, is there more to it?

Am I doing something wrong?[code]
View 2 RepliesWondering if it is possible. It works on the idea that all files share common code. The program would ideally analyse the source file and compare it to the reference files. It would then find common parts of the code and write it to a rebuild file. At the end the rebuild file and the reference files would then be able to rebuild the source file without it being present.
For Example.
source file code = xxyyzyzyxw
ref file 1 = xyxxzyzxwyy
ref file 2 = zxxwyzzywxx
The program would then analyse these files and make a rebuild file like the following
source(0,1) = ref1(2,3)
source(2,3) = ref1(10,11)
source(4,7) = ref2(5,6) + ref2(5,6)
source(8,9) = ref2(2,3)
Thus you would be able to build the source file using these instructions and the reference files.
I have an MDI form with 3 nested children with in it. As of right now all it can do is display a new form.For example: each time I press the menu button, the new child form(Form1) is created. Now, if I press that same menu button a second or subsequent time a new Form1 is created and it appears over the previous one.
What I would like is that each time the event handler is triggered (a menu item_click on the parent form) that instead of a completely "new" child form being produced(a new window popping up) it would instead pull up the appropriate child form that is attached to the trigger.
