• Windows Forms Combobox's behavior in dataGridView

  I have added a combobox column to the dataGridView control. However, when I choose something from the combobox and leave the cell, the selected value gets disappeared: the item changes to blank. I haven't written any code in any of the events. How can I make the selected values stay in the grid private void AddComboBoxColumns( int pInt_InsertAfterColumn) { DataGridViewComboBoxColumn comboboxColumn = new DataGridViewComboBoxColumn (); comboboxColumn.HeaderText = "Action" ; comboboxColumn.Items.Add( "In" ); comboboxColumn.Items.Add( "Out" ); this .dataGridView1.Columns.Insert(pInt_InsertAfterColumn, comboboxColumn); } ...Show All

• Visual Studio Express Editions Convert std::string to LPCWSTR (best way in c++)

  Hi! How can I convert an std::string to a LPCWSTR What is the best way to do it in C++ Thanks. "Ciao guaglio!" FabioDeSantis wrote: How can I convert an std::string to a LPCWSTR What is the best way to do it in C++ Instead of using a std::string, use a std::wstring (also called a std::basic_string<wchar_t>). I get the feeling you want to pass a std::string type to a Win32 API. Those APIs don't take LPCWSTRs (or even LPCSTRs), they take a LPCTSTR (long pointer to a tchar-string). In this case, your question should have been: "How do I convert a std::string to a LPCTSTR " Inst ...Show All

• .NET Development System.Web.Mail Help Please...

  Hello, I've tried searching and searching, but I've had no real luck. I'm working on sending an email via an external SMTP server (I'm trying to use Gmail.com, could this be a problem ) and then send to another email, which also happens to be a Gmail.com address. Now, before posting my code, I'd like to say, what I'm developing this for is basically a plugin for a program based on .NET 1.1, so I don't believe that System.Net.SmtpClient is an option, so therefore I'm stuck with System.Web.Mail.

• .NET Development Net.Framework Redistributable (dotnetfx.exe) - Can anyone redistribute it with an installer?

  Hi Net Developers I have written an add-in for Excel that references a .dll I wrote in Visual C++ and that includes some managed code. Therefore if I want to deploy it to other computers, I understand that I need to ensure that those computers already have Net.Framework installed on them, otherwise my dll won't work. While I have had no problem locating the latest version of the Net Framework redistributable dotnetfx.exe, I cannot find a Microsoft document confirming that a developer is entitled to redistribute the dotnetfx.exe file as part of non-Microsoft package. Does any one know where I can find confirmation that software devel ...Show All

• Visual C# Is it possible to "melt" multiple dlls into 1 large dll?

  Hi, We are developing a class library, and currently the library spans over several Visual Studio projects, both C#, managed C++ and unmanaged C++. This again means that we have several dll-files. When time comes to sell our class library, we would like to sell just 1 large dll-file instead of all the dll-files we have now. Finally, we use a few 3rd-party dlls and some unmanaged C++ dlls, which we also would like to "combine" or "melt" into the single large dll. Is this at all possible If not, how can we at least reduce the number of dlls I know we can combine e.g. all our C++ code into 1 project and get 1 dll and do the ...Show All
