• Visual C++ Experts please - Function problem

  Is there a function/header for executing a line of code from a string You might ask what this is for, it is for a dll wrapper. So i need to execute custom code which changes at runtime. Any ideas Thanks for any help provided. Regards, Christian Sciberras wrote: Is there a function/header for executing a line of code from a string Unless you include a compiler in your application, which will be both slow, expensive and generally troublesome: no, you cannot execute C++ code from a string. What you can do, is introduce Python bindings (or bindings to another script language such as LUA), and execute that from strings. Boost ( www.boost.org ) has a Python library, and for LUA you can look to http://www.r ...Show All

• Visual Studio Team System Javascript actions in coded web test not working correctly

  After reading the white paper of Josh ‘ Web Test Authoring and Debugging technique’ , I figured out that I could mimic the JavaScript action of a ‘ add to cart’ button for our product. Hence I coded my web test and included the following piece of code in the appropriate section request9Body.FormPostParameters.Add( "btnFinish" , "Add to Cart" ); There was already another ‘formpostparameters.add’ just prior to that in the same request. request9Body.FormPostParameters.Add( "Body" , "&Anthem_UpdatePage=true&__EVENTTARGET=btnFinish&__EVENTARGUMENT=&__VIEWSTATE=%2Fw" + However, this did not make any difference to the ...Show All

• .NET Development How to create AppDomains when assemblies reside in IsolatedStorage?

  The project entails a server that hosts the running of user code in sub AppDomains. A specific directory in a non-roaming IsolatedStorageFile contains the assemblies the user code references. For file system security reasons, it is desirable to be able to point the new sub AppDomain's base directory to a sub directory of the isolated storage file. Is there someway of doing this - without copying files to the actual FS For example, by refering to the actual ISF directly via:<SYSTEMDRIVE>\Documents and Settings\<user>\Local Settings\Application Data\<ISFName> How would the ISF's file name be determined in this case More generally, a furture requirement for the server is to allow cabinets or zip archives to be us ...Show All

• Visual Basic Non-WinForm wrapper for VB6 OCX

  A while back I successfully built a VB.NET user control as a wrapper for a VB6 OCX. I now have to do the same thing but for a non Win Forms application i.e. a ASP.NET app or a web service. Is it possible to build a .NET assembly that can be called from a formless application (another assembly/ASP.NET/web service) that wraps the VB6 OCX The control itself has no graphical presence only a handful of properties, method and events. Any advice appreciated. (Originally posted in the VB General section yesterday) I've searched all over the net looking for a solution to this - nowhere to be found. I must be stubborn, because I didn't really need to keep trying, but eventually I figured it out - for ...Show All

• Windows Forms Forcing a DataGridView to update values

  I've got a datagridview (winforms) controls with a collection bound to it.  Anyway, I've got a checkbox column in the grid.  I need its value to be updated to the object as soon when the column value is changed.  However, it only gets updated when I move focus off of that cell.  Is there anyway to change the way it behaves or call a method to force the grid to update values back to the bound collection   For instance, on a regular databinding to like a textbox I can change the DataSourceUpdateMode to OnPropertyChange.  Is there something similar to this for the entire DataGridView I'm having the same issue but with a combo box. Cellcontentclick event won't be fired when clicking the combo. What ...Show All

• Smart Device Development ActiveSync

  The activesync version I'm using is 3.8, and i'm developing in Visual Studio .NET 2003 in C#. I'm also using the mscomm.ocx for communication to the serial ports. I currently have an application open when I cradle my PocketPC. That works fine. But the point of that Application is to read data. I expect it to be just random characters, I just need to know that it is in fact communicating with the PPC. Any ideas on how I would go about this. I currently have the following as code (InitComPort is a subrouting I created that is initiated in the constructor) private void InitComPort() { com.CommPort = 1; com.RThreshold = 1; com.Settings = "9600,n,8,1"; com.DTREnable = true ; com.InputMode = MSCommLib.InputModeConstan ...Show All
