View 1 Replies.net - Bitmap Generation With Dot.net And Png?
Feb 2, 2011What 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. Let´s 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 2 RepliesAccelerate The Generation Of The MD5 Checksum?
Mar 17, 2010I'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.

View 7 RepliesC# - Tool For POCO Generation?
Mar 6, 2011I 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

Form Generation Over SQL Database?
Jan 13, 2010i 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?

View 1 Replies.net - MDI Child Form Calling, Not Generation?
Jul 7, 2009I 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.

The number of times is not known when the application is build.So form with the number of containers must be generated by code.

When loading the form a number is calculated. This number is used to show the number of containers.
View 6 RepliesVS 2010 Text Generation And Copy
Mar 20, 2011I 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.
