• Visual C++ How to pass BSTR* as the return value from the ATL\COM application to vb6.0 application.

  Hi All. How to pass BSTR* as the return value to Vb 6.0 client from the ATL\COM application and also variant data type as ret val to VB APP. Can anyone guide me on this implementation. Thanks in Advance. The MIDL declaration would be [id(1)] HRESULT FunctionThatReturnsString([out,retval] BSTR* retval); in the class header file: STDMETHOD(FunctionThatReturnsString)(BSTR* retval); in the class implementation file: HRESULT ClassName::FunctionThatReturnsString(BSTR* retval) { *retval = SysAllocString(L"Hello world"); return S_OK; } The pattern is the same for a VARIANT, use VARIANT* instead of BSTR*. Be sure to properly allocate and initialize the VARIANT in the implementation function. ...Show All

• Windows Live Developer Forums Straight line between two points?

  I want to plot lines between points on a map. I am trying to create an origin and destination map and can plot my push pins ok for the origin and destination, but I need to have lines connecting the two, not route lines, just straight lines so I know 1 point is associated with another. Haven't seen any examples of how to do this. See the interactive SDK ( http://dev.live.com/virtualearth/sdk/ ), under "Draw Lines". Basically, you just create a VEPolyline ( http://msdn.microsoft.com/library/en-us/VEMapControl/HTML/C_Namespace_VEPolyline_ctor.asp frame=true ) and specify the start and end points. Very easy!   Here's a complete code snippet that draws a straight red line across the top of Wyom ...Show All

• SQL Server Cluster Mirroring

  I've read a lot of the information about this topic in MSDN. My boss askme to understand and to let working an example application of Cluster Mirroring. The problem is that i dont understand well yet what is a Cluster and what is the main idea behind it. If someone really understand and can explain me clearly whats behind it, i will be very grateful. Thanks a lot for the help. ( Sorry for me english :( ) Ok, Basically a cluster is a two-headed monster. Chop one of it's heads off and nothing will happen, it will still carry on chasing you. In computer terms, the simplest cluster is a two-node cluster (two headed monster) , two physical computers sharing the same name and IP address. If one of the computers making up the cluster ...Show All

• SQL Server Report code and dataset question

  I have a strange (maybe not too strange) problem. I have data populating a report and everything is fine. This table also references another table where there might be zero to several prefixes associated with the name. If I have one row from the main table, but there are three prefixes that have to be concatenated to the beginning of the Name field (like a one to many situation), what would be the easiest way to do this I thought of doing a separate Report code and I have the following: Function addPrefix(byval current as string, newToAdd as string) as string dim deg as string deg = current + " " + newToAdd return deg End Function In the text box, I have it referencing it's own value. So the textboxes express ...Show All

• Software Development for Windows Vista How IEUser.exe and IExplore.exe communicates each other

  I am migrating a software that was running in IE (in XP, Win2k, ... but not in Vista). What this program does is to basically intercept (using API interception by modifying the iexplore import table in memory) the ShellExecute API. This is a compressor/decompressor soft. The problem is that when IE is in protected mode, it does not call ShellExecuteEx, but it "tells" IEUser that a given file will be executed. I would like to know how iexplore tells ieuser that a file has to be launched.... I've used several tools like Process monitor (from sysinternals) but I don't see any event neither file that is used... Thanks! In fact, when the user wants to "open" for example a do ...Show All

• Windows Live Developer Forums More tiles, please?

  Greetings, I see from the API that there's a way to implement a custom tile layer. Pretty cool, but for the project I'm brewing, I need more tiles (it's a granularity/server resource issue) at all zoom levels than the map engine uses. Is there a way I can implement this, or should I just roll my own tool Cheers, Bradford Oh, I think I misstated. I meant to say that, for example, you can have something like 16 tiles at zoom level 8. I need something like... 64. I don't see a way in the API to do this, however. ...Show All

• SQL Server Backup Maintenence plan question

  I have recently installed some maintenace plans to perform database backups for an application database. The database is in full recovery mode so I have setup a full backup to be run once per day and then transaction log backups to run every 2 hours throughout the day. My question pertains to the coordination within SQL Server with respect to the database backup and the transaction log backups. Let's say the full database backup is in progress and at the same time a trasnaction log backup is fired. What happens Does SQL Server just skip the tran log backup since it won't be needed or does it do the backup of the tran log anyway (in case the backup fails). Another question would be when is it safe to delete the transaction log backup ...Show All

• SQL Server History Id and SnapShot Id

  Hi, Wanted to clarify some doubts about Report History and Snapshot. 1. What is the difference between the snapshot id and history id. Report Snapshots are stored in the report history. When I call CreateReportHistorySnapshot method programmatically, the method returns a history Id. Is this id different from the snapshot id (report snapshot which is stored in the history). If the id's are different how can I get the snapshot id 2. The History id is a date-time stamp of the snapshot. This string is used as a unique identifier for the historical snapshot. It contains the time portion till seconds(not milliseconds). Hence if I generate the next snapshot in the same second it gets overridden. Is there any way to create more sna ...Show All
