I have been asked to create a Framework to be the basis of all our drafting toolsets. The approach I think is best is to outline all of the Classes that will be required (Text, dimensions etc), identify routines and properties required for the Classes and document in a spreadsheet.
View 2 RepliesI have learned to create programs in VB.NET with Visual Studio, but the downside of that is that i need the .NET framework, which is not on every computer. Can I create a program in VB.NET without it needing the .NET framework? If yes, what tools do i need?
View 1 RepliesI am essentially trying to create a list of records in VB.net using the 1.1 framework.It seems that I should be using an object even though I have only properties but no methods (more like a traditional record), I would like to store a list of objects, how can I create the list and add an instance of the object to the list.I do have sample code that almost works but it is too poor for public display.

View 1 RepliesI need to create a pdf file dynamically in vb.net. It needs to contain several images and lines of text. I am using VS 2003, so whatever solution I use will need to be compatible with the .net 1.1 framework. The current method I am using is wpcubed, but this requires that all images be converted to bmp format before adding them to the pdf, which can be extremely slow when dealing with a large number of images.
I am aware that there are an awful lot of other 3rd party products that claim to do this, and I have had a search through them. But without registering, downloading, installing and writing code to use each of them in turn, it is very difficult to differentiate between them. So far I have looked into evo pdf and pdfsharp,tallcomponents, [URL] but none seem to work with .net 1.1. (Although they don't make this abundantly clear.)

View 1 RepliesIt might be funny , but I'll ask anyway : is it allowed to create a program with VS2008 while at the same time it will use the Microsoft framework 4.0 ? I am asking because I use VS2008 while at the same time I have the impression that framework 4.0 is "lighter" than 3.5 .

In entity framework we can use 3 approaches model first , code first , database first but each one of them needs manual hand touch(means creating database or create model or write the POCO class codes or entity class codes) before proceeding to the next step ( using EF in context ).What if I want to create database and tables and table relationships programatically and still want to have to features of EntityFramework 4.3.
To be more specific ,from this example http://support.microsoft.com/kb/307283 we can create database , tables and everything using SQL command but we can't have the advantages of entity framework. So if we want to have that what should we do? To give the ability to create dynamic table fields those steps will not be sufficient. In all 3 steps database , table and table columns are fixed. There is no way that a user can create new tables or columns dynamically. http:[url].... in this post , it shows how to create manual db, tables and etc using SQL but it is based on ADO.NET but I want Entity Manager to do that.
i have my code as below in which i need to check the column(3) and column(4) for a condition and based on it i need to change color of the text and add some text to the value. Kindly guide for the same...

I am developing a program in which I add the payments for my bills on a monthly basis. I have the design layout and the logic thinking, but having a little difficulty getting the database codes in place. I have 2 comboboxes that act as drop down boxes (1 lists all 12 months and the other lists the years, only 2009 for now for testing).
My access database has 3 columns (name, dates, amount). The names are pre-populated and the only columns displayed in the datagridview are name and amount.
When I choose a month and year, the datagridview should populate with the amounts entered from that month. I am having trouble debugging which lines of code are not working because there are no errors showing, just seems that it stops running at some point.

I need to create a "post office" program that will send html emails thru the system.net.mail framework.
For each job submitted to the postoffice the app would need to read a user created html email string from the database, read a string of email addresses to send to and send out the emails based on a set processing time.
The first step would be to parse out the email addresses to find out how many emails it needs to send out and determine how many it would need to send per minute to complete the job in 20 minutes tops. I.e. if 1000 email addresses are submitted per job it would determine that it needs to send 50 emails per minute to complete the job.
The part I am stuck on is how I should queue the emails. If the app determines it needs to send 50 a minute should I only load up the first 50 on a timer event then get the next 50 queued up for the next timer tick? Or would it be better to load up all 1000 in a loop and build in some kind of wait time after it sends the first 50?

I have a solution that I wish to upgrade from Vb.net framework 1.1 to framework 4.0. The solution consists of a number of projects, all but one of which compile to dll's. The master project compiles to a executable which provides a menuing system which dynamically loads the dll's and connects to entry points.
The projects contain normal classes, numbers of forms and also controls, which are either usercontrols or are inherited extensions of standard windows controls.There are a number of third party components (eg reporting and grid controls from Component One, Ribbon control from DevExpress etc).

Several months ago, I asked someone here if it was possible to perform "DoEvents" on a conditional basis. This was for a VB6 application and it worked okay. It will not work in VB2010 and I was wondering if someone could tell my why?Error Message from VB 2010:
A call to PInvoke function 'MyApp.frmMain::GetQueueStatus' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.

I have a few programs published via ClickOnce. These are highly specialized programs, and are only used by a relative handful of people, but the set of users is likely to change, and is spread over a fairly wide geographical area. The major advantage of ClickOnce....ok, for me, the ONLY advantage of ClickOnce, is that I can create updates and have them (mostly) installed when the end user runs the program. Over the brief time that I have used it, I have encountered these aggravations regarding ClickOnce:
1) The application can only be installed on a user by user basis (it can't be installed for all users at once). I understand why this is done for a general solution like ClickOnce, but it is certainly an aggravation.
2) Updates don't always appear to happen. Usually, the updates do happen when a person starts the program, but a fair number of times, the update isn't noticed, or recognized, or something. This causes the user to continue with the old version, which makes them think that I didn't fix the bug they had, which causes them to give me a raft of excrement, which results in me flipping them the bird. Much hilarity ensues (fortunately, I'm friendly with my entire user group, so this is a fairly accurate acconting of the sequence of events, except that I just laugh at them rather than replying in sign language).
3) Certificates expire in a year. Certificates are a great thing...for some situations. In my case, an alternative seems like it might be better.
4) Some settings in the manifest are so doggone hard to fix that I've nearly given up. I changed the URL that ClickOnce was supposed to go to for updates, and found it impossible to change the program to find the new location. It had to be there somewhere, and I found several candidates, but never could find the critical one.
Because of these issues, I have been tempted to write my own replacement. There are a few issues that I'd like some commentary on. For one thing, security is an issue that is hard to pin down. None of the data I am dealing with is worth a second thought. No cracking of that data would harm anybody or any thing. However, my first thought would be to have people install an app that would go to a web service to check for the existence of an updated version. If one was available, then the existing program files would be overwritten by the new files. If one was not available, then no overwrites would take place. Lastly, if the service couldn't connect, then no overwrites would take place (of course). If the files were compressed for transport, it would be kind of difficult to intercept and inject a different program into the transport stream, so the only weakness that I can see would be if somebody hacked the server that held the new version, and replaced it with something else. What am I missing here?Also, has anybody done anything like this, and if so, what else am I overlooking?
