• Windows Forms DataGridView Object Data Sources

• Visual C++ DLL registration issue

  Hello, I am trying to register a DLL and failed. The DLL resgitration using regsvr32 command and it did not show any message. Usually it pops a dialog saying the registration suceeded. But this time there is no message at all. My client application can not find this DLL so I know that the DLL failed to register. The DLL is the output of a recompilation process of C++ code. The previous DLL of this source code works perfectly fine. Now I have to update the source code to accomodate new functionalities of the application. But I failed to register the DLL after recompiling the source code. May be I am missing some compilation options or so.. Any help with troubleshooting would be much appreciated. ...Show All

• Visual C++ How do I save a project with a new name?

  Hello and thanks in advance to anyone who answers this question which has been bugging me for a while. Once I have created a project, how can I access the 'save as' function which is available in many windows programs in the file drop down menu Is the 'save as' function unavailable for entire projects It seems like it would be useful so you could have access to different versions of complicated projects. I know you can 'save as' each source file, etc., but I can't figure out how to do it for the whole project. Thanks again, Jackson ...Show All

• SQL Server Query to see if an int field starts with a certain number

  How would I write a query on a table containing a column of ints, where I want to retrieve the rows where that int value starts with a number I know that you can do this with strings by using "....WHERE thisfield LIKE ('123%')", but if 'thisfield' is an int, how would I do this Thanks! I hate to ask this, but the giant pink elephant in the room is "how do you have an int that doesn't start with a number " What it sounds like you have is a column of string values that may or may not be an integer, and you want to see if the first character of the string is a number, right For this it is: thisColumn like '[1234567890]%' But if the column is supposed to only contain integers, the b ...Show All

• Visual C# dynamic asp button click doesn't work first time

  Hi all, I'm creating some asp buttons dynamicly and I associated them an event handler btnDel.Click += new EventHandler (btnDel_Click); but the first time I click on the button goes to the Page_load but the btnDel_Click is not fired. Somebody knows the reason Thanks in advance. P.D.: Sorry for my english. Hi, Whenever one is assigning event handler, it should be done prior to page load ideally. I think when you are assigning a event handler, that does not happen first time when page loads but when u do something, control gets added to the table and then you assign event handler. So somehow in ur code, u will have to make sure that each time page loads, event handler code should be ...Show All

• Visual Basic [HELP!!]How do I solve the nonlinear equation f(x) = 0 ??

  Hi, I am new to VB.Net. I am working on a program that needs to solve several one-variable nonlinear equations. For example, I have to solve f(x) = 0, where f(x) = c0 + c1*x + c2*x^2 + c3*x^3 + c4*x^4 - A c0, c1, ... c4 and A are constants. When given c0, c1, ..., c4 and A, the program should have the ability to solve f(x) = 0, and give back the value of x. At first, I try to use try-and-error process to find the roots of the equation, but it failed. I searched online to find if any codes are related to this subject. Unfortunately, I found nothing. So I ask for help here. If anyone can provide a useful algorithm for my question, it will be much appreciated. Thanks a lot for your help. I am using VB.Net 2003. ...Show All
