• .NET Development How to add Text to generated textbox

  Hi,   With a for loop I created 81 textboxes, all named t10[i ], they are created in Page_Load. for ( int i = 0; i < 81; i++) { t10[i ] = new TextBox(); t10[i ].Width = w; t10[i ].Height = 30; Panel2.Controls.Add(t10[i ]); and so on } Now i want to add Text to them on a later stage, for example while pressing on a button. like this: for ( int i = 0; i < 81; i++) { t10[i ].Text=array[i ].ToString(); } ofcourse nothing happens, when building, VS says t10 doesnt exist. How can I make a correct reference perhaps with the FindControl But than, wich objargs should I use thx ...Show All

• Visual Studio VS 2005 Plug-In can not be removed

  I built a quick and dirty VS2005 plug-in. Everything was working fine through several builds and runs (with debug), and then suddenly, it couldn't be built anymore because the DLL was already in use. What I discovered was that the plug-in was now permanently embedded in VS2005. When I go into the add-in manager, I uncheck all of the boxes associated with the plug-in, but it remains, even on restart. There is no Uninstall (there used to be, right ) in the project, and I can't find the plug-in in Add/Remove Programs. So, I can neither remove nor compile the plug-in. Any ideas -Vic I was able to resolve my issue by just removing the ...Show All

• SQL Server data modelling question

  Hi all, I need to develop some tables in SQL server to store formulas. These formulas can be of varying complexity. Some might take the form: 1 + 2 (ordinal1, ordinal2, operator '+') Others might take a more involved form: (calculation_from_a_field_in_another_table, random_ordinal, +) / (34 *2) And so on and so forth. The key point is that formulas can contain 1...n expressions and also a given term may be an ordinal that the user inputs, or it could be a reference to a pre-existing calculated value. I thought of: term_id, term_1 (NULL), term_2 (NULL) term_id_1 (NULL), term_id_2 (NULL), operator ...Show All

• Visual Studio Express Editions question about vb express and hanging the pc

• Visual C++ VC++ Documentation refers to cli/c++ syntax as the "new c++ syntax"

  "Visual C++ How to: Create a Windows Forms Application In .NET development, a Windows GUI .... applications in C++ use the .NET Framework classes and other .NET features with the new C++ syntax. For more information, see New C++ Language Features ." Don't want to be overly critical because I am impressed with the VC++8 compiler, ide and work done to increase compliance with C++ standards, but statements containing references to the 'new C++ syntax' is what makes the C++ community reluctant to see CLI/C++ become a standard, because it could muddy the water between C++ and CLI/C++.
