• Visual C++ Mixed mode finalizer bug in C++ class destructor with std::vector member

  I have discovered a bug when finalizing a CLR class which deletes a data member which is a pointer to a C++ class, and the C++ class has a std::vector<ANYTYPE> as a data member. When this occurs an exception is thrown, with the message in the debugger being: "An unhandled exception of type 'System.AccessViolationException' occurred in msvcm80d.dll Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt." Breaking in the debugger shows that the exception is occurring in the stack trace from the vector's destructor code, with the last source code trace being line 45 of xmtx.c in an _Mtxlock routine. Tracing the bug shows that the finalizer has executed afte ...Show All

• SQL Server OLEDB Destination Error in SSIS Package not returning error column/desc

  I have a SSIS package that reads data from a dump table, runs a custom script that takes date data and converts it to the correct format or nulls and formats amt fields to currency, then inserts it to a new table. The new table redirects insert errors. This process worked fine until about 3 weeks ago. I am processing just under 6 million rows, with 460,000 or so insert errors that did give error column and code. Now, I am getting 1.5 million errors. and nothing has changed, to my knowledge. I receive the following information. Error Code -1071607685 Error Column 0 Error Desc No status is available. The only thing I can find for the above error code is DTS_E_OLEDBDESTINATIONADAPTERSTATIC_UNAVAILABLE To add to the confus ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. DXT compressed Textures

  Hi, in general it looks like there are the same DXT texture compression formats as for DX9. I assume those compression formats do not work with the new DXGI_FORMAT_R9G9B9E5_SHAREDEXP & DXGI_FORMAT_R11G11B10_FLOAT formats In real-life (TM) I always have to store texture data in DXT compressed formats ... if I want to opt for a better color quality in compressed formats, nothing seems to have changed between DX9 and DX10 ... is that correct Thanks in advance, - Wolf :-) .. it depends on your requirements. If you run a renderer without gamma correction == gamma 1.0 ... you are pretty lost. Here is a list of formats: - the new RGBE format and RGB can not convert to gamma 1.0 - a common form ...Show All

• Smart Device Development Why is my filter/search results showing up twice in the Listview?

• Visual Basic ComboBox setting a value - Help!!

  Folks, After using VB 6.0 for the last 10 years, I am rather embarrassed to post this question because I could not find answer to this question. Here's my situation 1) I have a dropdown combobox. It displays a the list of projects.

I have to set proper "SelectedIndex" property based on the value passed to to this form. How do I do it I see methods like "FindExactString", "FindString" etc. I can use them if I passed the "Description" value from ...Show All

• Windows Forms FolderBrowserDialog - Can't select network computers

  I'm working on a simple VB app that will allow me to inventory the computers on my network. The difficult part (getting the PC inventory details posted into SQL) is all but complete and now I'm working on tidying it all up. I want to be able to add the above control so that I can select a computer within my network for use within my program i.e. "please select the computer you wish to inventory". 2 things (1) the folder browser control doesn't seem to be able to select a computer rather than a folder, can this be changed and how and (2) is there a way to force the root folder property so that it default to the domain in my network. Any help, greatly appreciated. Cheers, Sumpty you can set ...Show All

• .NET Development Windows virtual memory Page File increases a lot, when running my application

  Good Morning for everyone, I have a C# application that when running ~2 days it increases very much the windows virtual memory, taking windows xp displaying a systray message balloon telling that windows virtual memory is low. The physical memory is OK about 300MB , but another thing (regarding taskmanager) is also the number of hanlges and I/O Writes that the application has. Its all managed code, i only have an unmanaged active-x that makes image acquisition from a camera. Code has some threads that access to a database, and writes every 3 minutes 4 BMP images abot 3MB in to disk, and some textfiles used has logs. . Does anyone know how to avoid this, or does someone know how to handle this correctly TIA, Tiago Teixeira Hi Chris ...Show All

• Visual Studio Team System Building UN-managed code within TFS..

  I have several Team Projects working as desired - I now want to create a new Team Project which contains mostly un-managed code and I'm looking for suggestions/help/examples/etc... In our old environment (VSS) the projects were built using 'NMAKE' and worked without issue, but I would like all code within TFS Source Control and I'm curious how others have managed what I believe is a fairly common occurrence. How to build un-managed code using TFS Thank you. You can use MSBuild Exec task to call the compiler of unmanaged code to build that unmanaged code as part of total build. You may also create and use custom task to do the same. You can call any of these from a target which overrides " ...Show All

• Visual Basic Code to Flow Chart Diagram

  I'm looking for ideas... I have written an app to generate a logon script for my domain, and I'm pretty happy with it as long as I am willing to hack the vbscript, but I want to be able to generate the code based on objects in a diagram. Let me explain a bit... My app shows users, groups, OUs, printers, drives, etc. in listviews, and it's easy enough to drag a printer or a drive onto a group or a user, but suppose the printer is dependent on what workstation the user is logged onto. I think it would be do-able to display a picture box, parse the vbscript and draw lines and boxes, but that would only be an output - very useful, but that only makes a logon script viewer. I would have to be able to give the user buttons and whatnot to draw ...Show All
