• Visual FoxPro How to change assigned class libraries.

  Hi; I have often backed up my working folder to seperate sub folders like 'backup' etc. I have just noticed that in my project the class lib for some of the classes is the class lib in the backup folders. I am not sure how this happened. Is there a way to reassign all existing classes and objects so they use the one in my development folder Thx. Alenko, It's entirely possible too though that your forms and classes contain references to these backup classes. After you make adequate additional backups of everything. You can USE TheForm.SCX and repair the ClassLoc field with a REPLACE ClassLoc with strtran( ClassLoc, "\backup", "" ). Issue a COMPILE FORM TheF ...Show All

• Smart Device Development Visual C++ Express for WIn CE?

  I started to learn VC++ Express, and assumed that since it generats managed code for FORM applications, I could just copy the working app. to my CE mobile, but it is not working. What do I have to do in order to have the portabilty (same manged code runs on mobile or desktop), or, if this is impossible , what do I need to do in order to have a working app. on my mobile Thanks. C++ generates native code, C++/CLI generates managed code. Whatever it is, you can not develop for devices with Express. C++/CLI is not supported by NETCF at all, native C++ is supported on devices by VS 2005 SE or above. To sum up, you can develop for devices with native C++, C# of VB.Net using VS 2005 SE or above, E ...Show All

• Visual C++ any comments about a cache design?

  Hello everyone, I am going to design a Cache in C/C++ (memory cache). I have two different approaches to design/implement it, any comments will be appreciated. Design 1, using a map (hashtable) to store key --> object pointer relationship (simple and straight forward); Design 2, store real object or object pointer in a stack/linked list/queue/array as an internal storage data structure, then using a map (hashtable) as an external interface to mapping key --> index in the stack/linked list/queue/array; (in this design, when accessing an object, we need two times mapping, first mapping key to index in the stack/linked list/queue/array, then using the index to access the real object) I am wondering any advantages or disadvantages of th ...Show All

• Smart Device Development Signing and compression questions

  Hi, I wonder if you guys could help me clear something up. I am new to the compact framework and indeed Windows Mobile in general - I have been reading up extensively recently but there is a couple of things I'm not totally sure of. I have read conflicting information on MS.com / msdn / blogs First i read that smart phone apps MUST be signed. "CAB files for Smartphone solutions must be digitally signed before they are deployed to an end-user's device. or use certain APIs". Then I read this "How you get "trust" is determined by the OEM or operator selling the device. For some devices, all apps are trusted. For others, you get trust after the user agrees to a prompt. For a large number of devices, however, to be tr ...Show All

• Visual C# Where *is* the right place to ask for C# book recommendations?

  A thread asking about C# book recommendations was recently closed. The reason cited was: I will close this thread because this was asked several times before and there are great sites like Amazon that provide readers reviews and voting for books. However, no guidance was given as to where the *right* place is to ask for C# book recommendations on these forums, which was a bit of an omission, IMHO. Why should we have to go elsewhere to ask these very pertinent questions We should be able to ask for book recommendations here. (*Not* book reviews!) Given that the description of this very forum is: General discussion and questions regarding Visual C# 2005 -- incl ...Show All

  Now with XNA will you be making the game right in XNA, or do you like make it with another program using different code and then just use XNA to make it playable on the 360 Thanks! Hello, Your game must be written using C#(At least for our first release) and using the XNA Framework to run your game on the Xbox 360. You could use a different IDE to do this but not different code, you'll still need the IDE to deploy(copy) the game to your Xbox 360. ...Show All

• SQL Server Memory problems & package performance

  Hi, I know the SSIS memory problem has probably been covered quite a bit, but being a newbie in using the SSIS, I'm not quite sure how to improved the performance of my SSIS package. Basically, I've a package that loops through all the subdirectories within a specified directory, and it then loops through each file in the subdirectory and with the use of the Data Flow, process each file (according to their filenames) with a Script Component to insert data into a SQL DB. Each subdirectory has up to 15 different csv files, but each is less than 5kB. I probably have about 100 subdirectories. When I run the package, it functioned properly, but the package stalled (no error but just stuck in one Data Flow) after a while, and when I ...Show All

  is it possible in current version of DX10 in Vista setup desktop resolution as static In result if any application tryies to change resolution, DX change it virtually, but actually will work with desktop resolution. I think it would be nice to have this feature for current LCD displays, which is not good to support natural resolutions. I haven’t seen something like this yet. Additional it would be dangerous to use a different resolution as the application request. ...Show All

• Smart Device Development How to Increase the Pocket PC 2003 Emulator Device Memory ?

  I am running out of memory when deploying a vb 2005 application (with sql ce). So I want to increase the emulator memory Using VS 2005 I have gone into tools>options>device tools>devices>Pocket PC 2003 SE Emulator>Properties>Emulator Options> .. tick Specify RAM Size, and put 64, 128 or 256 in the ram size box. Then I kick off the emulator either by running the vb project or by running it from "Device Emulator Manager" - my setting seems to be always ignored and the device memory is showing as 29.70MB. A hard reset of the running device does not solve the problem. Neither does rebooting the PC. Any ideas thanks  note I am able to kick off the emulator manually, using this command line....

• SQL Server SQL 2005 Express slow/stalling

  Hi All, I've read a few threads on problems that look similar to my issue, but I can't seem to find a solution. Is there any particular reason a queries should take longer than normal to execute And I don't just mean a couple of seconds... Some times a query can take about 0.01 seconds to execute (which is good) and others it takes 25 seconds to execute (which is bad). This anomaly seems to occur on all websites using the database instance. The only thing I can think of is something to do with the server running as a Windows user as opposed to System. The user (system.mssql) has no special rights except for log on as service, plus all the normal (modify) permissions on the SQL-related directories. If anybody could give me a ...Show All
