• Visual C# Runtime - Progress bar

  OK. What I need is to make a progressbar at runtime, which is no problem, because I know how to do that. But heres what I want, when I click a button, I will create a progress bar, and then when it fills up, I need to know how to make it go away, and then create a label, the text being "hello". Can someone explain to me how to do this Hi, A faster approach would be creating a progressbar and a label at design-time then set the visible property to false. When you click the button, just make the progressbar visible and populate it, after populating you can hide the progressbar and show the label...     cheers, Paul June A. ...Show All

• Visual C++ Needed information on size_t datatype

  Hi all, Can someone explain me: - The use of type size_t - Why do we use size_t , if other datatypes are available size_t is a platform dependent type. size_t is 32-bit on a 32-bit platform and 64-bit on a 64-bit platform while this is not the case with our traditional datatypes such as int, float. If we are porting a 32-bit application to 64-bit platform. This type causes a lot of warnings. warnings of the type: y:/include/datum.cxx(443) : warning C4267: '=' : conversion from 'size_t' to 'int', possible loss of data Please suggest solutions to remove this kind of warning. Also send me the relevant links if p ...Show All

• Visual C++ Some insight for a new C++.net developer

  Good morning experts: It is beginning to become a little frustrating finding some basic information for somebody new to the .net environment in regards to c++.net 2005.

• .NET Development Can't Add Reference to DLL

  I created a class library dll in VS 2005. I can add a reference to the dll in other VS 2005 projects. I can also use the dll from VB6 (I added all the correct interop stuff). However, when I load up a VS2003 project and try to add a reference to the DLL, I get an error that tells me that the dll is not a valid assembly or COM component. Is it not possible to use .Net 2.0 DLLs in .Net 1.x Thanks, Ned You might be able to get it to work outside VS through the command line but VS 2003 doesn't support v2.0 of .NET. From what I have heard from MS developers VS is tightly coupled with the version of . ...Show All

• .NET Development Opening an MS Access Database In Exclusive Mode Using ADO.Net

  Hello All, I am having a bit of a problem here and I am hoping that someone can shed some light on how to solve it. In both DAO and ADO you have the ability to open an Access database in Exclusive Mode. I cannot seem to find a connection string parameter that allows you to achieve this in ADO.Net. Does this functionality exist in ADO.Net If so, what is the correct syntax for this portion of the connection string Any help you can offer would be greatly appreciated. Thanks In Advance, V.

• SQL Server sync_type parameter in subscription

  Hi, I tried to change the subscription property "sync_type" whith a system procedure but I was not able to do it, because sp_changesubscription does not support this property. Is there any chance to change this property by procedure So I decided to drop the subscription and define it new with sp_addsubscription. I chose to set this to "replication support only" as the value "none" is depricated based on the online help. Unfortunately using this value results in an error message "only none or automatic is allowed". How can I set this value now to "replication support onl ...Show All

• Visual C++ Poly-Threaded C++ Applications

  I have a few programs that I am converting to be threaded. At present I have a couple of programs, computer chess engines, that are threaded and work fine with Microsoft's C++ compilers. When the SMP.H #define's detect _WIN32 || _WIN64 it calls up process.h functions but on other platforms it need to use a bit map in ASM to manage the threads properly. Other considerations include inter-process communications etc. If threads dont need to speak to each other then the situation is simple, if not then some form of signalling is needed and the program becomes more complex. One program I use computes end game positions for chess, usin ...Show All

• Visual Basic Dynamically populating a combo box .?

  I am trying to populate a combo box on a form based on the contents of a field within SQL. i.e. I read the data from the SQL field.  In this case I return the string "Select * From Transactions" I populate my dataset and set the dataset as the datasource of my combo box.  This works fine. However what I want to do is to use a where clause in my select statement such as "Select * From Transactions Where AccNo = '" & strAccNo & "'", where strAccNo is a variable within my VB app. Now not surprisingly my combo box is empty as the the datasource is exactly as my select statement reads and it is trying to return records where Acc ...Show All
