• Visual Studio Express Editions how to limite data displayed in a listbox?

  I have a listbox "listboxServices" and an ACCESS db table "services", when i set the listboxServices' databinding to the default dataset, the listbox will show all the data in the services table. Instead, I want to list all services that have a null value in "DatejobDone" column in table "services" (i.e. all pending services). please help. btw, I created a new query for table "services" ---- "FillByPendingServices(), GetDataByPendingServices()", the sqlquery is something like : "SELECT ............ FROM .......... WHERE DatejobDone IS NULL " but no idea if it's what ...Show All

• Visual Studio Express Editions Unbound Checkbox

  OK, I have my datagridview all set up - mostly with data from a table but I have a couple of unbound columns. In particular I have a checkbox column. Now I capture the CellContentClick event so I can "flip" the checkbox from on to off and vica versa when the cell is clicked... But for some bizarre reason I can NEVER change the value... I set the value to FALSE or TRUE but they never seem to take effect.... The code worked fine when I has NOT in virtual mode (the datagrid) - as soon as I switched to virtual mode it all stoppd working... Am I missing something Thanks, Simon This is in the CellConten ...Show All

• SQL Server How To Audit DML Table Changes w/o Triggers?

  Whenever any DML activity occurs in a database I need to audit the following: 1.  The table that was changed (INS, UPD, DEL) 2.  The data value of the primary key of the changed row For example, if someone executes: UPDATE payroll SET Salary = 50000 WHERE empid = 123 I need:    "payroll" and "123" For various business reasons I can't use triggers.  It is just one of those things... I've looked at various options on SQL Profiler and while it looks like I can tell there was an action on the "payroll" table it doesn't look likely that I'll be able to figure out that it was on primary key 123.  This s ...Show All

• Smart Device Development Port eVC4 to .NET Compact framework

  We wish to port a program (developed in eVC4) on the .NET Compact framework. This program calls a proprietary native library provided with the device we used and the vendor does not plan to provide a .NET library for this device in a near future. Our goal is to rewrite the program in C# but we do not want to spend many time to write a wrapper for the native library (which proposes a C++ API). Is there an easy way to build automatically a .NET wrapper from the C++ API (perhaps with eMbedded Visual C++ Upgrade Wizard addon to Visual Studio 2005 or an other tool ) Else, is there an easy way to call methods of a native library from C# code on ...Show All

• Visual Basic Thread Debugging

  Hi, I am currently developing a multithreaded network app, debug output shows a couple of first chance exceptions, however if an exception occurs that is not first chance i.e. bad mid() statement, the ide just freezes for a few seconds, no pop up and i cant trace through the app. What am i doing wrong I have disabled Just My Code, although i doubt this would affect the debugging of my code as it is all managed anyway. I would also like to debug the first chance exceptions if at all possible. Is there something in the IDE settings i have missed Thanks for your time. Matt. I have worked out what the ...Show All

• Visual C++ Using map as DLL function parameter

  Hi, I'm trying to create a map object in main program and give pointer to this map to function from dll as parameter. When then I want to use this pointer in the dll function every attempt at iterating the map leads to program crash. It is peculiar because methods as size and even access to first pair of the map works normally. Thank you for help. That's the problem with statically linking the CRTs. As you should know, std::map uses dynamically allocated memory to store it's map as you add entries to it (or you construct/destruct/copy construct), and particularly for iterating entries. You'll get crashes wit ...Show All

• Smart Device Development Emulator remote connection lost during debugging

  I have VS 2003 installed and use the emulator 5.3.0.26 with the WebPad sample image (Windows CE 4.2) for testing. The emulator is connected as a Windows CE Device with TCP Transport. Everything work fine, but if I stops in debug mode more than 2-3 seconds on a breakpoint, the connection to the device will be lost with the message: "The remote connection to the device has been lost. Please verify the device connection and restart debugging." This effect doesn’t depend on the application I debug. I guess that somewhere is a parameter to increase that timeout period. Does anybody knows a solution Remark: With the built in emulator in ...Show All

• Visual Studio Cast problems writing Add-Ins in C++.

  I know, maybe it will not be a new question, but for the moment I wasn't able to find a real good answer. I was writing some Add-Ins for Visual Studio, and I chose to write them in C++; what a big mistake! Microsoft really hates people trying to use this 'old fashioned' language. You can understand it just looking at all those code samples around: nearly all Visual Basic or C#... So actually I found a solution to my problem, but not for C++. My question is really simple. If I have this: typedef ATL::CComPtr<Office::CommandBarControl> IDECommandBarControl; typedef ATL::CComPtr<Office::_CommandBarButton> IDEComm ...Show All

• Visual Basic Locking a member Variable in Memory

  Variable life time is normally not a problem in VB but but I'm working in the context of a webservice and variable persistence is quite different. In a normal VB program Member variables are the variables common to all routines.... and not declared in a function or subroutine. They are assumed to have a lifetime for the lifetime of the program. In a normal program I can do this: Class    Member variable    Subroutine A    Subroutine B end class The member variable has a lifetime of the program. Static is not a legal option for a member variable. The environment in a webservice appears to be quite ...Show All
