• SaraD How to update DB from dataGridView using OdbcCommandBuilder ?

  The full text of my program is below. Form has 2 buttons and a data grid. Button 1 fills a dataset with rows from either a local Dbase table or rows from a SQL server table - depending on which connection string you choose to use. The rows show up in the data grid and I am able to edit the data within the grid. Button 2 attempts to update whatever changes have been made to the in memory dataset back to the physical database. After making changes within the data grid, clicking button 2 yields the following error: "The ConnectionString property has not been initialized." No matter if I am getting data from the local Dbase table or from the remote T-SQL server table, I get the same error. I'm stumped. Am I out of scope on s ...Show All

• AdeptBlue abstract properties : get; vs. set; vs. get; set;

  I would like to define an abstract property where the deriver is forced to implement the get acessor for that property but is free to implement the set acessor. It seems that C# 2.0 has no way of declaring this. Either the deriver has to implement both acessors (get; set;), or the deriver is not allowed to implement the acessor that was not declared in the abstract base class. I am suprised that acessors abstractness can not be controlled separately since the ultimately end up as methods anyway. Why is that so   James Curran wrote: True, but you missed a key point made by the OP: Instances of these derived Types will be displayed in a Windows Forms Propertygrid where the user ma ...Show All

• David Noy problem with SortedList

  Good Afternoon- I'm having a problem using a SortedList to store objects. Here's the example code: public override SortedList derivitives() { SortedList s = new SortedList(); s.Add(xyz,dxdydz); s.Add(uvw,dudvdw); return s; } The code fails during the second Add, with the following error: Unhandles Exception: System.InvalidOperationException: Operation is not valid due to the current state of the object. in System.Collections.SortedList:PutImpl in System.Collections.SortedList.Add in System.Collections.MyClass.derivitives() ... I tried an example code with SortedList and I can Add() as many strings as I want, is there a problem with SortedList holding abstract objects they are all of the same type... thanks, Philski ...Show All

• JunoJun does managed code take precedence over native code?

  i wrote a small demo C app that sends a message and a struct to a managed C++ dll. this C++ dll marshalls over the message and struct to a managed struct and sends it to a C# assembly that just prints out the values of the struct (to see that everything came over ok) and sends back a string reply, it also prints some debug text to console. before the call to the C++ dll, i make a few calls to printf to print to console. when it runs, it does the C# assembly debug statements before the native C printf statements. other than that everything looks ok. does managed code take any sort of precedence over native code the whole thing is a proof of concept. so the quick and dirty: ok so i have a C# assembly, i ...Show All

• Bill Baker Uploading With Webservices!

Any help will be appreciated... Thanks! Rick van den Bosch wrote: You state you have a webservice to upload a file. I take it the webservice has a description as to how you should upload a file using that webservice. If you want to develop a webservice to upload a file, that's another story.

• Azriel Cross New bug added in VS 2005 SP1? "Unreachable code detected" warning.

  Has anyone else experienced this The following code now generates a warning saying "Unreachable code detected". This is new since applying VS 2005 SP1. The warning is given on the throw statement below. public DateTime CurrentTime { set { if (value == null) { throw new ArgumentNullException(); // Error here. } currentTime = value; } } It implies that the value passed in to the setter could never be null which is obviously not true. I just started getting this warning after upgrading with SP1. DateTime type is a value type and obviously cannot be null ! Thanks! I always forget that.
