How to register COM object when created in VS2005 Express ?
I've tried checking Register for COM interop in Project Properties->Build , i've tried Regasm.exe utility and still when I try Add Refrence -> COM , that object is not there...

Now when I checked warnings, there is a Warning: "C:\Documents and Settings\stefanz\My Documents\Visual Studio 2005\Projects\Test45_COM\bin\Release\Test45_COM.dll" does not contain any types that can be registered for COM Interop. I've done everything according to Creating simple COM objects using interop

Hey Guys,
I've got a asp.net web application. Its a simple application which connects to a SQL Server 2005 Mobile database. I would now like to write a windows application which will wrap this asp.net web application and allow it to be executed normally.
I was thinking of using the in-build webdev server somehow in the windows application. Then, add the webdev.exe to the setup project of the windows app.
Can this be done? If so, how would I go about doing this? I have been searching on google, and will continue to do so. I haven't found a info on this topic.
Thanks.

Hi!
I am facing problem when inserting large amount of data in XML file. I am using C# 2005. I am using XML file as a replacement of database table. My application stores as many as 100000 or more records in XML file, but it takes too much time in inserting/retrieving these records (almost 1-2 minutes).
I have made such insertion before but at that time structure of each node of XML was very simple with no child nodes, it took 1-2 seconds to insert 100000 records at that time. But now structure of each node is different. Each node contains 5-6 child nodes..
Previously i used MS Access for this purpose but faced same problem so switched to XML, now the data insertion/retrieval time is reduced almost 5 times but my problem is not solved, i want to insert/retrieve 100000 records in maximum 15 seconds.
Please tell me why this problem is occuring, can XML be used as alternative of database? If not then how can i obtain required results...? is there any thing else available for this, other than database and XML...
I put this question in XML/XSD board but i was adviced to consult C# group..
Thanks in advance...

No. XML should be used as a data transport mechanism between disparate systems. It should not be used as a database.

Perhaps you database schema was not optimised for what you want to do.

The amount of records you are trying to process seems a bit excessive for a xml file. I would rather look into something like mysql or sql 2005 express. Both are excelent and should have no trouble in handling a lot of data.

Although this an old article it may enlighten you http://www.codeproject.com/soap/xmltiming.asp[^]
XML can be used as a small datastore. Note the SMALL, yours is to large for this to be a viable option, as you have found out. I would suggest using SQL Server Express or SQL Server COmpact Edition.
only two letters away from being an asset

I would certainly suggest you to look at SQL server 2005, At first place it come with XML data type which is much easier. You can do all the operations on SQL server and if required convert it to XML ...

hi all  ,
I'm working with listview to insert and update data directly into that listview (so you can imagine that user wants to fill data just like using MS.Excel). Oh ya, actually it's a simple purchasing and sales program and I'm using listview to input, update the records of every Item that has been purchased or sold and below the listview, I add one textbox to count the total of purchasing/sales of all items in the listview.
thanx in advance,

I am not sure whether this is a C# or COM issue, but I thought I'd try it here.
We have been building a COM wrapper around a C++ API which needs to be accessible from C#. This seemed to work and run fine as a win32 build with.
Converting to x64 however, despite everything seeming to compile, and being able to access the COM stuff correctly from a c++ application, as soon as we try to add it to C# everything seems to go wrong.
Normally one can click "Add Reference" and then select the type library from the list - and this works fine in x86/win32. However, with the 64bit build, the type library does not appear, and selecting the dll manually gives errors implying that it does not contain any COM components - despite working fine with a c++ project.
Looking in the registry etc. the correct entries seem to be make under HKCR/Typelib/<lib>/win64... exactly as for the win32 case - but I still can't see it from C# in visual studio, or VB for that matter, so I am somewhat at a loss...
Has anyone got any ideas as to what to look for

I'm just taking a wild stab here but it's probably because C# is by default 32-bit. This page[^] seems to back me up.
[edit]Looks like you can modify the build properties of the C# project for "Any CPU" to host 64 bit processes.[/edit].

Thanks, but we had already switched the build properties to x64 for all the applicable project options.
On further investigation, it appears to be some form of registration issue, as such COM rather than C#. Using OleView it gives a "Library Not Registered" error, despite it showing up in the TypeLib list, and the registry keys appearing to be set exactly the same as for the 32bit build, except for win64 rather than win32.
The really obscure thing is that when I cheat and change the win64s to win32s in the registry it all seems to work despite the registry keys being blatantly wrong :-s, as it should be able to support both win32 and win64 simultaneously...
Anyway, I'll probably go and poke some COM people at some point rather than C# people.

hi every one
how to find the error in xml file.
i am writing a application in that iam using xml file.
but if any error in xml file that exe not working.
i want to know error in xml file while opening my application.

Load your xml file in an XmlDocument object inside a try-catch block before at he beginning. If you catch an exception close your app or show a message to the user or do whatever you need.
|
|
|
|
|
There is a utility called Notepad++ a and XML plugin available at same site. Try that, if you are working with larger amout of data, it will save you a lot of time and nervers ))
|
|

I would suggest you to create an XSD (schema definition), This will validate the XML for correctness. After loading XML, Use the validateSchema method and pass required XSD and check for the correctness.
Hope this helps

I want to draw class diagram inside visual studio 2005 web application. I know that i can add a new item of type "class diagram" to my solution but the .net class diagram is very poor. I can't add multiplicty for my relation. I can't add an association class. I can't make a dependency between two classes. so, can anyone help me to find a better way to draw a good class diagram and to get the generated C# classes from it?
Thank You
Ahmed Amin
