I have stripped this down to a very basic html page of the following:
<pre><html>
<body>
<form name="aspnetForm" method="post" action="PortalLogin.aspx?ReturnUrl=%2fportal%2fetaportal.asp%3fapp%3dCWA" id="aspnetForm">
<script src="/ETASSOPortal/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=ctl00_RadScriptManager1_HiddenField&compress=1&_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d3.5.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3aen-US%3a94b8a2b4-5efc-4f4c-9641-d912b698978d%3a52817a7d%3bTelerik.Web.UI%2c+Version%3d2008.2.1001.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3aen-US%3a9638cb27-0c96-4947-a8f4-d97afe664a61%3a393f5085%3a34f9d57d%3a5edc7ae2%3a251a9451%3a526d426%3a81330300%3ac6335cbd" type="text/javascript"></script>
<script type="text/javascript">
//<![CDATA[
if (typeof(Sys) === 'undefined') throw new Error('ASP.NET Ajax client-side framework failed to load.');
//]]>
</script>
<strong>Looky Here</strong>
</body>
</html></pre>
And it appears the actual line that is causing the problem is the line of "<script src =......". When I added this line, my small example produced the same error as my original post, and then when I take it out, the error goes away.
Anybody know what might be causing this error?

The System.IO.Ports.SerialPort class is what you need.
There are several articles about it here on CP.

Hey guys, I never thought my post would appear the way it did on the page.
Sorry for any inconvenience. this is my first time posting so i guess I really dont know how the Message editor of the forum works.
Sorry.

It is not too bad for a first message. You even managed to publish formatted code, something that is rare in the VB forum for unknown reasons.
[EDIT]Breaking up your SQL statement to reduce the source width would have made things more readable though...[/EDIT]
FYI: you can still edit your message, after you have posted it. And you can reply to it if you want to add information. There is no need to start a new thread at all, keep it all together, that is easier to all of us.

Hello experts,
I am really stumped on this one. I have a VB6 front end tool to log in customer queris and the corresponding resolutions with start and end timestamps, customer name,email, phone number etc. Each customer interation is logged into the database via the application into the database and needs to be tagged with a unique ID.
The requirement is that I need to generate the ID every time a new case is logged in the program and save the information to a temporary table first and then push it to the main table. this is ecause there are multiple users for the application and in order to avoid dupliation of the Case ID I have used the "idReturn" sub procedure to find the last updated ID and increment it to log a new case in the table.
The problem is that the new case ID does not enerate in spite of the procedure I added , because the query in subprocedure "cmdUpdate_Click()" does not update the main table form the temporary table. Easch user would run an instance of the application from his or her own systema nd according to the a parameter set from the login form, another field called "RepID" will be updated in the table whe they log a case by clicking on the "Update" Command button after which the next Case Id should be generated. i guess I am kinda looking for a Token system to make sure that when a record has been updated with a unique case ID, the next user to press the update button to log a case should e given the next new unique ID dynamically created to store in the database.
Any suggestions? Or could someone please direct me to some examples of Multi_user database programs in VB6 with similar record lock criteria?
I can send anyone the source code if they wish to analyse it further.
The database record would look like this
ID Date Month Weekday Time Originator CustName.. etc

The problem with generating the case ID first is that two users can get caseIDs before either one is written to the database. Your primary key shouldn't be generated and should NOT be calculated until the record using it is written to the database. You don't checkout a case ID first, you get it last, after certain minimum data is written to the database.
Also, Access is NOT a good candidate for a multiuser database. Yes, there are people around here who will argue that point, but I've supported too many of these and had to fix too many problems with them to given these people any credit.

Hello Dave,
Thank you very much for your input. I tried it. First, I had the user form update the temporary table via ADODC control and then wrote a query to insert the record to the main table from the temporary table. Then I used the data1.recordset.delete method to delete the temporary table.
The problem is the data is not transferrin from the temporary table to the main table but the temporary table is deleted. The result is that there is no addition to the main table.
Could you help me with this please?
Regards,
Kumar

Simple, don't use a temporary table. You're just needlessly making more "round trips" to the database and doing stuff that isn't really buying you anything.

Thanks a lot for the advice. I just created a record off the fly and used it to retrieve the ID with minimum value and "Flag=N" meaning it has ot been used for ay update. Then , I insert the data based on the text fields in my form. then I change the "Flag" field to 'Y' to say that this particular record has been used and use the followind method. Then I used the "idreturn" method to return the lowest value of ID with Flag=N. Worked like a charm!!! Absolutely no multi-user conflicts since each user would be opening a different record at the same time.

I got promoted to System Analyst on Friday a couple of hours after I showed my manager this program. This makes it the 7th app I have developed since I joined work October last year.
Thanks for your support.

That's all well and good, but what if a second user runs the same query and it shows up exactly between the time user number 1 runs that query, and then runs the query to change the flag to 'N'? Trust me, it IS going to happen. Flags like this just don't work in a multiuser environment. If the operation requires more than a single step (query) to "checkout" an ID, you will end up with this problem. Maybe not today, maybe not next week, but even a year from now, it's bound to show up. The chances of it happening also increase with the inevitable increase in the number of users using this database.

Hello all,
I need a small help in resolving an error
I want to create a folder with time and date
I am usingthe code,
MkDir ("c:\moved\PK3\" + str(Hour(SystemTime)) + "." + str(Minute(SystemTime)) + " " + str(Day(Systemdate)) + "_" + str(Month(Systemdate)) + "_" + str(Year(Systemdate)))
for creating a folder inside " c:\moved\PK3\ "
Most of the time its work fine. But some times an error will come as "Path/file access error".
Its not happen often . How to resolve this error?
Thanks and regrds

Post the full exception detail include the full message, stack trace and everything else.
From the info you've given my best guess is that you are trying to create a directory that already exists. (because you've already run the method once in this minute)

Hi.
I'm a spanish developer, i need to implement a 2D Closet designer very similar to this: http://www.ikea.com/ms/es_ES/rooms_ideas/pax_step_by_step_08/index.html
The system must do this:
1. drag items with texture, from the menu to a design area.
2. drop in the area in function of the properties, for example:
- Object_A, can drop only in the base of the closet.
- The size of the Object_B is from point A to the point of collision in the near object
- We can put the Object_C, only from top to bottom (move restricted in x direction).
3. The user can edit the position and the size of any object in any time.
Did any of you know resources (tutorials, examples, templates, libraries, plug-ins...) that can help me to finish saving time?
I have a little problem of time.
Thank you.

Hi
When i try to break point (Debug) the vb.net program. then program not stop at the break point and when we move the cursor on break point it shows the following error "Debugger problem "The breakpoint will not currently be hit. No symbols have been loaded for this document"
i also change the configuration setting to debug mode. but success is so far.
Please suggest how i solve this problem
Thanks

When you are debugging a program, the debugger (visual studio) needs to locate and load the matching symbol files (the .pdb files) for the specific version being debugged.
It's possible that the .pdb files for some reason are getting mismatched. Perhaps there are some old .pdb files hanging around from an old build. Try deleting everything in the bin and obj directories of every project. This will cause all the projects to rebuild fully and regenerate their .pdb files.
If this doesn't work, check the project settings to see if it's configured to generate symbol files. (Right click on the project->Properties->Build tab->Advanced->Output:Debug Info. Set to either full (for debug builds) or pdb only (for release builds).

If you are still unable to get that to work, you can right click on the breakpoint, choose locations, and enable the "allow code to be different" checkbox at the bottom. This will let you debug code when the deployed PDB/DLL doesnt match your debugger copy.
