• Visual C++ calling managed function from unmanaged c++ causes exception

  Hi, i have a problem with a my dll loaded as a plugin in external application (Bentley Microstation). I compiled my dll with /clr switch. The dll can be loaded, and functions that dont contain managed code can be executed, even code which uses COM interop for calling components in C# works. But when the application calls the function which contains managed code - it fails with a exception: First-chance exception at 0x7c812a5b (kernel32.dll) in ustation.exe: Microsoft C++ exception: [rethrow] at memory location 0x00000000..

• Software Development for Windows Vista SqlTrackingWorkflowInstance lose ActivityEvents

• Software Development for Windows Vista capicom.dll -- redistributable?

  I'm trying to figure out a way to redistribute tools that will allow end users to sign their installers and binaries. According to the SDK license, signtool.exe is not redistributable. It is my understanding that we cannot redistribute signtool.exe. However, it seems that signtool.exe calls capicom.dll -- and capicom.dll is redistributable and can sign binaries. But, the SDK redist.txt file doesn't list capicom.dll. However, other Microsoft web sites list Capicom as redistributable (e.g., http://msdn2.microsoft.com/en-gb/library/aa382434.aspx ). So, Is calling capicom.dll a recommended approach to signing binaries. And, is it in fact, redistributable Is there any backdoor options to redistribute command line tools or dlls that ...Show All

• Visual FoxPro appending to a grid

  ok - this is kind of a weird question - is there a way to append to a grid in the background What I would like to do (if it's possible) is to still have functionality to my form while the program is taking the time to append. Does that make sense If so is that possible Forgive my inaccuracies - It's grabbing from an SQL Database and copying to a cursor which is bound to the grid. The basic reason why I need it is b/c when grabbing from larger databases, it's a stand still wait (sometimes up to 3-4 mins if the database is extremely large). I guess a more appropriate question would be how to grab asynchronously and display it like you had said The way it's running right now it waits till the entire thing is loaded and then displays... ...Show All

• SQL Server Service Listing Manager Question for Remus

  Hi Remus - Thank you for your Service Listing utility. I am very new to S.B. I had an intern working for us do some research work into S.B. and I gave him your utility to use for the work I gave him to do. Here is what I am trying to do. Very simply, I want to setup a remote (target) server that many other source (initiator) servers will send messages to via S.B. I had the intern learn how to have a single initiator server send messages to the remote server. He used your utility to create the SQL script that needs to be run on both servers to get things set up, and it works correctly. The script below is what your utility created to be run on the remote server. The reference to 'SDDev2' below is a reference to the initiator (source) ser ...Show All

Any advice would be much appreciated. Does anyone have any suggestions or perhaps another angle that I could approach this problem Thanks 1. I am not exluding the possibility this to be a bug. We also ran into an issue with large reports where the reports will time out. The forthcoming SP2 is expected to fix this. 2. Also, I would suggest you contact the Support Center ASAP and request a hotfix. The best thing will be if you could send them a test harness. ...Show All
