Read How to get an answer to your question[^]. Next time please give the proper Subject line not like "hello?". Then nobody will not contact you through your mail id.

My suggestion is just create documentation, design the architecture, then UI design, code. When you feel trouble/doubt in your code, ask question here. Many people here to help. All the best

In one single answer to this question? I hardly think so.

At the beginning: learn VB.NET, the Speech API, Office Interop etc. If you have no idea about any of these then I doubt that this is the best choice for your thesis.

I thought the point of a thesis was to write about something you are expert in, or research it and become an expert in it. A thesis by google does not seem like a worthwhile pursuit. I suggest you start by buying a good book on programing in .Net and go from there.

No, the school would have prepared you and taught you how to do it, unless you parties through all the years.

Start by utilizing what you had learned, start researching on the subject matter.

Hi guys, a settings question, and this forum group seemed to fit:

Using VS2008 I go to create a 3.5 project, and it inserts "linq" namespace automaticly. Yes I can delete it, however I would like to change it so it's not a default add. I remeber seeing it somewhere once in the past where I can modify the default namespace adds, and I remeber I was able to do it back in VS6 for c++, is there a way to do it with VS2008?

thanks for input.

These defaults are found in the project templates located in C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\ProjectTemplates. You can try changing them, and it does the job, however I believe the templates may get overwritten during any updates to Visual Studio.

Getting OutOfMemory error in 3.5 Windows app after upgrading server memory

Paul Brower6-Mar-10 2:41

Re: Getting OutOfMemory error in 3.5 Windows app after upgrading server memory

6-Mar-10 2:41

We have a windows 2003 - Enterprise server (32bit os) that previously had 12GB memory. We've upgraded it to 32GB, and now our .net 3.5 Windows application is getting an out of memory error when we run it. (Don't think it matters, but we're hitting Oracle 10g, SQL Server 2000, and MySql 5 databases).

Nothing in the program has been changed, only the server memory.

Any thoughts? I've been googling for 3 hours and have nothing. The memoryLimit in machine.config seems only to apply to ASP.Net apps.

Not much help I'm afraid, but MSDN[^] states that there's a 16Gb limit for the 32bit version of W2k3 Enterprise, and that you'd need some special configuration[^] to use it fully up to the 32Gb limit.

Well, we've got 32GB in there, with no other problems.

The error only occurs when we're hitting the MySql database.

Thus it's limited to MySQL and .NET; are you using MySql Connector/NET[^], or another provider? Is it replicatable in a small test-project?

Re: Getting OutOfMemory error in 3.5 Windows app after upgrading server memory

6-Mar-10 8:47

Yes, I'm using version 6.2 (latest) of MySql connector for .net.

My problem here, is that it is only a problem on our server that now has 32GB memory (upgraded last night from 12GB).

I can't duplicate the problem in a dev environment ... only prod. I'm not about to install visual studio on that server either. It HAS to been a bug in .Net 2.0 or 3.5, or a bug in MySql 6.2 -- only an issue if you have 32GB memory? I don't know.

Let's find out; if you create a small console-application (on the dev pc), targetting .NET 2.0, using ODBC, can you query the database (when running on the prod pc?)

SOOOO embarrassed about this, but I feel like I must post, so as not to further dissuade anyone from using MySql.

As it turns out, the code the was executing in production, somehow (um, me) was double-building an inner join.

So, instead of something like this:

select s.id, s.tag, s.gline, s.sex, bdCal.yyyymmdd as birth_date
from weaner_83 s inner join calendar bdCal on bdCal.dddd=s.birthdate
where id in ('X05008869E1G7','X05028869E1G7')

I was getting this:

select s.id, s.tag, s.gline, s.sex, bdCal.yyyymmdd as birth_date
from weaner_83 s inner join calendar inner join calendar bdCal on bdCal.dddd=s.birthdate
where id in ('X05008869E1G7','X05028869E1G7')

These ids can only exist once in the table. With these two Id's, i was getting 380,000 records. Why, you ask? about 190,000 records in the table, and 10,000 in the calendar table.

Of course my actual code was query much more than just these two id's.

I'll probably never know how this happened, but most assuredly it's my fault. Now it's fixed, and i've burned a good 8 hours.

Thanks for you willingness to help.

WindowsFormsHost invalid theme in WPF Application (.Net 3.5)

6-Mar-10 1:15

Quoted from MSDN[^]:
The .NET Compact Framework is a subset of the full .NET Framework. It implements approximately 30 percent of the full .NET Framework class library and also contains features and classes that are specific to mobile and embedded development.

The normal Windows Forms control do not support WPF themes, nor Aero Glass. You have to replace the controls with ones that do.

You may want to look into a third party control library if you want to get up and running faster, or put the time in to develop your own.

vb.net, check array elements?

golisarmi4-Mar-10 5:33

I need to check all element of an array to see if all are equal to 1 or 'T' then do something.
how can i do this?

My first guess would be to iterate over the array and check the values, but of course that may be to simple for you to figure out.

loop cant help because, may be I'm missing something

for i=0 to array.length-1
if array(0) = 1 then
check = true
else
check = false
end if
next

this doent work for me because if the last element is 1 then the check(boolean variable)becomes true while it is possible that other elements for example first one is not equal to 1. but I need to make sure are all of them (all elements) are equal to 1 or not.

Help please
