• .NET Development How to get the left digit value?

  Hi Is there any function is available in Managed C++ to get the left side value of Integer value for example, that function should return the interger value like this... leftvalue(19,1) = 1 leftvalue(25,1) = 2 Assume leftvalue() is proposed function. Thanks in advance Jose  Hi, If my memory serves me right, then InStr() - gets the location of a specified character(s), Mid() gets a substring. If thats the case then: String^ test = "Microsoft"; // INSTR() int idx = test.IndexOf('o'); //Mid String^ str = test.substring(1, 5);   cheers, Paul June A. Domag ...Show All

• SQL Server Suspect Mode (no icon in SQL 2005)

  In SQL 2005 when a database is in suspect mode there is no obvious way to tell (via SSMS). In SQL 2000 the word "suspect" was displayed (via Enterprise Manager) next to the database, and the respective database icon was grayed out. Why was this behavior changed for SQL 2005 From a disaster recovery standpoint, it is very important to see immediately if a database is in suspect mode. Hi, I've checked with the SSMS team and this look like a bug. Can you please submit feedback through the Microsoft Connect system ( http://connect.microsoft.com ) This way we can notify you when the issues is re ...Show All

• Visual C# command prompt return immediately when running console application

  By default, a console C# app will hold the command-prompt until the app exits. Is there a setting in the .NET framework that will cause the command-prompt to return immediately This is sort of analogous to running a command in the background in unix by appending & to the command. Hi. The responsables of doing that are the shell and the OS not the C# language or the .Net framework. The OS because it must support Multitaksing (ms-dos does not) and the shell because it must do some system calls, ex fork (not exists in ms-dos) and exec, in order to provide that functionality.

• Windows Forms Bindingsource.Filter Problem

  I have a Windows Forms app with about 20 combobox controls on one form that are databound to a dataset from a SQL 2005 Express db. In addition to the comboboxes, I have one DataGridView that uses a bindingsource (MaintenanceBindingSource) as its datasource. I want to use the filter property of the bindingsource to filter records from the dataset based upon the value (text) of the SerialNoComboBox and display them in the DataGridView. I've tried the examples of the following code in the TextChanged event of SerialNoComboBox, but none seem to work: Me .MaintenanceBindingSource.Filter = SerialNoComboBox.Text MaintenanceBindingSource.Fil ...Show All

• Visual C++ need english

  Getting ready to work on another lab for school and I'm having trouble understanding the lab. This is the program they want me to write: Write a program that declares two twenty-element, one-dimensional integer arrays. Your program should fill these arrays with random numbers by calling a function called Fill_It. You will call Fill_It twice, once for each array, and ask the user to enter two different seed values. Fill_It needs to have a seed value, and low and high range values, and all three integers should be passed to it along with the array. Fill_It will use the seed for srand and then fill the arrays with values between the low and hig ...Show All

• Windows Forms Is it possible to change a colored form to grayscale temporarily?

  Hi, I just have an application that show many forms at the same time so in order to keep the users concentrated on the main form, I want to change the other forms to be grayscale temporarily and change them back later. Anyone has got idea how to do this Place a panel and change the Dock property to Fill. On the forms Activated event you add panel1.Enabled = true; In the Deactivate event you add panel1.Enabled = false; This will gray out all controls in panel1 (that contains all controls of the form) whenever it loses focus and enable them as soon as it gets focus. ...Show All
