I have created a form for a user to create a booking of a meeting room, I need this form to do 3 things.have print functionality update the new booking to a dataset view the current bookings screen I seem to be struggling with the second task, when I try and save my new booking I get this error
System.InvalidOperationException was unhandled
Message="Update unable to find TableMapping['mtrbookings'] or DataTable 'mtrbookings'."
Please see the code for my form.
Imports System.Data.SqlClient
[code].....
I have not declaired any data sources, like a data grid view or the text boxes from which my information is typed by the user (text boxes).
An unhandled exception of type 'System.InvalidOperationException' occurred in system.windows.forms.dllerror in line: dbAdp.Update(dbDset) in btnSave_Click, (elseif editflag = true) blockdescription: Update unable to find TableMapping['Table'] or DataTable 'Table'I was also wondering if I could simply use the ExecuteNonQuery for the delete statement, but since I've placed my data in a datarow, I'm not sure if i can actually use it. Any thoughts on this? Btw, this is my first time using a datarow, and I've recently been studying how to use ADO.net.
dr = dbDset.Tables(0).Rows(CurIndex) dr.Delete() dbAdp.Update(dbDset.Tables("addresses"))

I am working on a silverlight project in which i am using the entity data model. I have a consol application in the same solution through which i am creating the database table at runtime. Now when i moves to silverlight page i need to Communicate (load data from newly created tables).But problem is that without updating the model how i will able to communicate with that table at runtime using entity framework model.
we changed the mapping from the table per concrete class to the subclass strategy and now the UnitTests fail, but I cannot recognize why.There's one base class Article and a child one SemifinishedArticle with no specific properties.
I have three tables in my SQL Server DB. I need to import some CSV files into these tables. First table is a Order Table, which will contain all the order level information from that customer in that CSV File. Each order has multiple items and the second table is an item level data. Third table is a mapping table which shows the mapping for each customer . for a Customer say A ,
I'm using Visual Studio 2008 on an XP machine. My other machine died so I had to re-install VS on a new machine. Everything worked find until I went to the new machine. Now I keep getting these 2 messages below when I go to build my solution:
Unable to find dependency 'interop.stdole' (signature ='(null)' Version='2.0.0.0') of assembly axinterop.mscomctllib.dll Unable to find dependency 'interop.stdole' (signature ='(null)' Version='2.0.0.0') of assembly interop.mscomctllib.dll
I tried to remove the references to both .dll's and then re-add them in and that didn't work. I tried removing and re-adding stdole, and that doesn't work either. I tried installing VS on another machine, but I get the same messages there.
The only thing I noticed out of the ordinary is under Detected Dependencies, when I right-click on axinterop.mscomctllib.dll and view the dependecies, I noticed there is a yellow exclamation point in the icon for interop.stdole. I don't see any information regarding that exclamation point however.
I have developed a windows based application using visual studio 2005 called DMS. On the client side, this application runs on asp dot net framework 2.0. We have created its setup file which has to be installed on the client pc. After the installation of the application, some of the users get the error message as:
DMS.exe - .net framework initiation error Unable to find a version of the runtime to run this application
(I have also attached the screen shot of the error message.) Trouble shooting done by me:
a. I had tried the re-install Dot Net Framework 2.0. b. Scanned the PC for virus attack. c. Install dot net framework 2.0 first and then the application. d. Un-install and re-install the whole application.
But none of the solution works. The only thing that works temporarily is un-install the whole application and re-install it. Then it works for a few hours.
I have written an application that calls 'My.Computer.FileSystem.SpecialDirectories.Currentm UserApplicationData'. My application is working fine, but one user has reported an issue that has me stumped. When this property is accessed, the following exception is thrown:
"Unable to find an entry point named 'VerLanguageName' in DLL 'version.dll'". The stack trace says that the exception came from Microsoft.Win32.UnsafeNativeMethods.VerLanguageNam e(Int32 langID, StringBuilder lpBuffer, Int32 nSize)
I don't think the problem is with my code. I suspect that there is something wrong with a system-level component on her computer, particularly with the DLL that is mentioned. Is this DLL part of a specific windows component that could be reinstalled/repaired?
I just installed Lucida Grande font on my computer and I am unable to find this font when I add a label or text box control. I can see the font in the control panel and MS Word. What is the right step to see this font?

I'm looking at writing a application that interfaces with TAPI via the samsung open TSP. The problem I'm having is that after a few days research I am unable to find much info regarding coding for TAPI. There also appears to be alot of contradicting information out there too...
Has anyone got any pointers, examples or sources that I can start looking through??
I don't think I can use my student account visual studio for commercial purposes. However, I can't afford eight hundred dollars for visual studio. I talked to a Microsoft rep and they said that with the visual basic express edition I won't be able to code anything or debug anything.
Does everyone here have visual studio professional or above? I was studying hard on my visual basic so that I could get started doing contract work on my own and hopefully start a software company after I get out of school. Now I don't know what to do. My next thought is to keep working on my C++ so that at least I can develop and deploy apps with free IDE's.
I have a program that will print dwg and idw drawings to different printers. from our drawing vault we kan use a plotbutton which creates a pcf-file (text file) and copies the drawing to a specific location. the program reads the pcf file which contains the max printsize for the drawing, who is printing it, nr of copies, location of the drawing. all data is written to or read from a small database. as long as there are drawings the printing goes fine, they are listed in a datagridview on the form. As soon as the last record is removed from the datagridview I get the following error[code]...
I have a web site that uses the both c# and vb.net in the app_code section. The different languages are separated into their own folder and correctly configured in the web.config.
This works fine 95% of the time. In production using 2 load balanced servers I sporadically receive an error message along the lines of:
"Unable to find assembly 'App_SubCode_BasicCode.xxx, Version=0.0.0.0, Culture=netural, PublicKeyToken=null'.
The site is hosted in IIS7 and I think it has something to do with the name of the dll assigned during dynamic compilation. I do not see this problem in a single server environment. Could this be because when the session is balanced to the second server the dynamic compiled dll name is different?

I've tried to incorporate this code in my app and can't figure out what the missing link is? Lotsa experimenting and head scratching later, I'm coming here to the forum for help. The dialog opens and allows me to select the file saved earlier,except the file doesn't open. I can't figure out the missing code which goes at the comment "insert code to read stream here." The code:

does it have something to do with StreamReader.IO ?
