• .NET Development Calling a .NET component from VB6

  Hi, I'm new to VB.NET programming and am attempting to create a .NET class that I can call from a VB6 program. I've created a .NET class and a VB6 calling program and have been able to successfully call the .NET class from the VB6 program when I run it locally on my machine. I've installed the .NET framework on a Windows server and have registered the .NET class using the following command: regasm C:\VBNET\DEVELOPMENT\InvAdmissionsCOM\InvAdmissions\InvAdmissions\bin\Debug\InvAdmissions.dll /tlb: C:\VBNET\DEVELOPMENT\InvAdmissionsCOM\InvAdmissions\InvAdmissions\bin\Debug\InvAdmissions.tlb This seems to register the file succesfully. I then try to reference this from my VB6 application. I can browse and see the InvAdmission ...Show All

• SQL Server Data disappearing during Run time

• .NET Development CodeDomProvider Parse Method

  Unfortunately the method is not implemented and returns a NOT_IMPLEMENTED exception. I want to be able to create a CodeCompileUnit from source code to be in synch with the Workflow Designer. Using IEventBindingService I can genreate CodeMemberMethods but when I load the generated sources from disk I need a way to re-create the CCU to be in synch. VisualStudio seems to be able to do that. There is an internal class which seems to be able ... Any hint would be very much appreciated. ...Show All

• Microsoft ISV Community Center Forums Hybrid between Cells.Select and ActiveCell.CurrentRegion?

  Hello guys, Assume I have data like this. Each < > Means a cell. < > Means nothing in the cell. <A1><B1> < >< > < ><B3> If I use Cells.Select, the range will be ("A1: IV65536") too much selection. If I use ActiveCell.CurrentRegion, the range will be ("A1:B1") not enought selection. I wish to select the range ("A1:B3"). What should I do Thank you. Edit: Hello NVM. I found a way to do it. I use previous search on * from the last cell. Why didn't I thought of that before, silly me.     Thanks for the reply, but I don't know the boundary of the data. I can't specify it.

• Visual C++ _mbscpy_s pointer confusion

  Hi All! I'm new to cpp and getting severely beat up by some pointer stuff. I have an unsigned char array buffer with some data including the length of a string followed by the chars of the string. This byte array is received from a client via socket - all that works fine. I am trying to call _mbscpy_s to get the string out of the buffer: BYTE buf[BUF_SIZE]; // 1024 // buf bytes look like this buf[0] = 0 next four are length of 'name' buf[0] = 9 buf[0] = 0 buf[0] = 0 buf[0] = 0 'name' starts here buf[5] = 112 'p' buf[ 6 ] = 97 'a' buf[7] = 114 'r' etc. Now, the code: unsigned char* name = new unsigned char [iNameLen]; // length is 9 errno_t err = _mbscpy_s( name, iNameLen, &buf[5] ); throws a 'Buffer too small' exception but errno_t err ...Show All

• Software Development for Windows Vista Vista - Media State Unauthenticated

  Hi all, I am building a Wireless Utility. It uses WPA Supplicant at the backend instead of WlanSvc. It works fine for Windows XP and 2000. But in windows vista I have faced a typical problem. My supplicant succeeds to connect to a AP - at least "Network Connection" shows the adapter as connected and the MAC address of my adapter is also visible in the attached Device List of the concerned AP. But if I use "ipconfig" tool from command prompt it shows the media state of the Wireless adapter as " Media Unauthenticated ". It does not show any IP address againest my adapter and I fail to have the cionnectivity as well. Since this Utility/Supplicant works fine for Win XP and Win 2K, it seems that Vista is pla ...Show All

• Software Development for Windows Vista Seeking problem with VMR9

  Filter graph consists of 2 source filters: 1. Source filter (which is used to playback AVI file) 2. Custom source filter (which implements CSourceSeeking, based on Seeking Ball example) - push model, ARGB32 subtype uncompressed images As a renderer i'm using VMR9 with 2 input pins, each one for one source filter, in windowless mode. The problem is when I seek (using IMediaSeeking interface obtained from FilterGraph), filter graph seeks only the AVI file, but not the my custom source filter. I've tried debugging and none of the seeking methods are called within my custom source filter. Thank you in advance! Thats what it appears to do for me as well... Intrestingly enough the SDK specifies th ...Show All

• Smart Device Development Help with assembly missing

  I am porting a VB6 program to VB .NET CE and get this error when trying to run my app on the emulator...

• Visual Studio 2008 (Pre-release) Subscribing to a PageFunction's Return event from another Window

  I have a series of PageFunctions and two Windows. One window is the main window for my application, and the other is a window that just contains a Frame. From the main window, I launch the second window, and pass a PageFunction to it that it navigates to. Before creating the window I subscribe to the PageFunction's Return event. The PageFunctions work and allow me to navigate through each one. When I reach the end I call OnReturn(), and it calls OnReturn for each PageFunction along the way recursively, exactly like the sample code. However, the Return event that I subscribed to from the Main Window is not called - I cannot comprehend why. Am I right in assuming the Return event has something to do with a NavigationService that my Mai ...Show All

• SQL Server SSIS clustered, accessed by multiple instances

  Hi, I have a clustered environment which has many instances in it. I have modified the xml file to allow several instances to use ssis. Everything works great when the instances are on the same node as the clustered ssis. However if they are on different nodes there seems to be an aunthentication problem and it loses my credentials. For some reason it tries to use Anonymous Logon instead. Here is the full error: The SQL server specified in SSIS service configuration is not present or is not available. This might occur when there is no default instance of SQL Server on the computer. For more information, see the topic "Configuring the Integration Services Service" in Server 2005 Books Online.
