upgrading source code from .net framework 1.1 (vs2003) to 2.0 (vs2005), i am facing error msg "Class not registered" for Interop.MOZILLACONTROLLib.dll.
please help!

You should re-install your control library (as you did when you were using the 1.1 framework). Note that you'd better check if there's a new version.

|
|
|
|
I think you need to register library Interop.MOZILLACONTROLLib.dll
using regsvr32.

Interop libraries do not need registered, they are .NET assemblies.

By raw values, I mean the application level values provided by UI controls, such as the Text property on a TextBox. Too often I find myself writing code to check and parse such values before they get used as a business level value, e.g. PaymentTermsNumDays.
I've mitigated a lot of the spade work with rough and ready extension methods like String.ToNullableInt, but we all know that just isn't right. We can't put the whole world on String's shoulders.
Do I look at tasking my UI to provide business values, using a ruleset pushed out from the server app, or open my business objects up a bit to do the required sanitising etc. as they required? Neither of these approaches sits quite right with me; the first seems closer to ideal, but quite a bit of work, while the latter doesn't show much respect to the business objects' single responsibility. The responsibilities of the UI are a closer match.
Between these extremes, I could also just implement another DTO layer, an IoC container with sanitising and parsing services, derive enhanced UI controls, or stick to copy and paste inline drudgery.

I have made a window application with MS access database to analysis student performance in his class for each exam that he appeared for.
I have a table named result with following fields:
classname,sectionname,subjectname,exam type ,rollno,studentname and marks.
On one form I have taken crystal reportviewer and 5 comboboxes for selecting class,section, subject, exam(first,second,final or unit tests), and student name.
After selecting these values , click on button to generate graph of his marks for each exam.
I was able to generate graph for one student for any particular class and section.
But the problem is that the graph is not generating for for other exams and other students.
My code is able to give graph for one student and not for other.
Kindly help me in resolving this problem and provide me with some solution.

Are you aware of any spreadsheet like application (incl. Grids) that could be run on .Net Micro Framework?
Appreciate your information.
Thanks,
Srik

Thanks Jinal, for referring a very good site.
btw, if you come across any of the KB related to a custom made lib that renders a spread sheet like UI using micro framework, pl pass on. I appreciate all your help.

thanx to the replies for my previous post i registered a dll using gacutil.exe , but now when i'm trying to use it in a project i tried to add it as a reference , but it is not displayed in the dialog box, but that dll is shown in the "c:\windows\assembly", any idea why this happens.
and need another clarification , when we use drag and drop we put the dll in the
"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727" for version 2.0. but when we use gacutil.exe the dll is in the "c:\windows\assembly", can anyone explain what is the difference of these two folders and what is the folder called "gac". as i read gac is the folder "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727".

GAC is Global Assembly Cache, http://msdn.microsoft.com/en-us/library/yf1d93sz(VS.71).aspx[^].
I'm trying to remain positive and encouraging, however if you don't know this, or at least know enough to Google it, then you shouldn't be doing .NET development.

The listed 'GAC' assemblies shown in the add references is not sourced by the GAC. Visual Studio holds various reference paths in the registry that point to the physical, non-GAC location of the assembly. eg. "C:\Windows\Microsoft.NET\Framework\v2.0.50727" which holds the 2.0 assemblies.
While you can add your path to the registry it would be simpler to just browse to the dll an add the reference.

thanx . i thought vs 2005 get all the dll which only from GACs

int n = int.Parse(CustomerID[CustomerID.Length - 1].CustomerID.Substring(4, 3)) + 1;
i try this to generate customer ID but kept telling me the is clash with surburbID becouse i linked surburb in customer table

Dear Kolisa,
have you tried something like that:
int currentMax = CustomerID.Max(customer => int.Parse(CustomerID.Substring(4, 3)))+1;
I assume you use c# as your choosen language in version 3.x. If not, pls specifiy your problem in more detail. Besides, i suggest to give your variables more distinguished names. Have an array with name CustomerID of type CustomerID is a little bit confusing. Also int.Parse on a substring without null checks or length checks is quite dangerous.
Regards
Jens

You have given very little context. What is surburbID? I assume a foreign key. What does your data structure like? How are you assigning the id? We can't read your mind and we're not working on the same project with you.

i wrote this code to retrieve size from the database
private void grpSize_Enter(object sender, EventArgs e)
{
string size = "";
if (rdbLrg.Checked)
{
size = "Large";
}
if (rdbReg.Checked)
{
size = "Reg";
}
if (rdbSupa.Checked)
{
size = "Supa";
}
i am using this to pass it to the next from
frmOrderDetails order = new frmOrderDetails(lstItems.SelectedValue.ToString(),rdbSupa.Checked.ToString());
order.Show()
but what it does shows me true when i click the size i want and show false when i click other button i want it to retrieve the size i putted on the database
|

can you post code where you retrieve size from database
based on the selection ??

Why are you passing the ToString of a boolean? That is asking for trouble.
If all the radio buttons are in the same group you should add else before the 2nd and 3rd if statements. No reason to check for all 3 every time.
I also don't understand why you wouldn't pass size to your second form.

Hi All,

This exact same code works fine on one of our other machines. Is there some .NET setting that needs to be added/modified on the machine that is recieving this error?
Any help would be greatly appreciated.
Thanks,
Mel

Hi Mark,
Thank you for your reply. I added the AllowPartiallyTrustedCallers attribute to the assembly of the application but this didn't solve the issue.
Let me given more imformation. I have a webApplication that has the dll file (let's call it App1.dll) of a windows application in it's bin folder, which I have also added as a reference. App1.dll is where AUser() is created from and in turn AUser.VerifyCredentials() is called in line 37, which is giving the error.
I added the AllowPartiallyTrustedCallers attribute to the assemblyinfo.cs file of the App1 project and then copied the new App1.dll file to my webApp's bin file again and re-added the reference.
Am I missing a step? Is there something else I need to carryout?
Thanks,
Mel
