[MI-L] Network problem
Dear List One of our customers is occasionally getting this message:- Table xyz has been changed by another program and must be reopened. The files are being accessed from a server running Windows 2003 Server. The user is running MapInfo version 7.8 on Windows XP. They assure me that they are the only user and only application accessing the MapInfo table. The table is a native MapInfo table - not linked to Excel or Access. One possibility is that their original files are corrupt and I am planning to check this. Has anyone else experienced similar problems?

[MI-L] VB.NET & Integrated Mapping
I've never had any problem sending commands to MapInfo from a VB.NET application. I can run all sorts of MapBasic commands and launch MBXs. But I haven't figured out how to reference the individual MapBasic applications I've started to access their RemoteMessageHandlers or invoke their RemoteQueryHandlers. How does one properly set this up in VB.NET? Best regards, Cory Martin ___ MapInfo-L mailing list MapInfo-L@lists.directionsmag.com http://www.directionsmag.com/mailman/listinfo/mapinfo-l
RE: [MI-L] VB.NET & Integrated Mapping
The things you want to do are done via DDE. Look in your MapBasic user's guide under "How MapInfo Professional acts as a DDE Server". Since I've never attempted to do DDE in VB.NET (sort of has the feel of pulling a wooden plow with a Ferrari, doesn't it?) you're on your own as to how to initiate and use DDE conversations in that environment.

Re: [MI-L] VB.NET & Integrated Mapping
Hi Cory,
The running mbx's can be accessed from the MIPro object by traversing
its MBApplications collection, like this :
For Each mbx In mipro.MBApplications
s = mbx.Name
If s.ToLower = "relevantapp.mbx" Then 'found it
Exit For
End If
Next
Then it's just a question of invoking mbx.Do('') or mbx.Eval('')
Remember that .net is case sensitive, most likely also with the mbx file
names. Thus the ToLower string comparison.
A caveat I found, is that mbx objects need to be defined as "Object".
The MapInfo Interop assembly doesn't seem to handle it very well as a
typed variable.
Best regards / Med venlig hilsen

RE: [MI-L] Dynamic expressions in select clauses
Or you could use the Alias variable to hold the table and column names Dim aCol As Alias, selColumnId as integer, selColumnName as String selColumnId = selColumnName = ColumnInfo(MyTable,"col"+selColumnId,COL_INFO_NAME) aCol = "MyTable." & selColumnName select aCol from MyTable HTH, Peter Horsbøll Møller GIS Developer, MTM Geographical Information & IT COWI A/S Odensevej 95 DK-5260 Odense S.

HTH Spencer From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Francois BlancSent: Thursday, October 05, 2006 10:23 AMTo: mapinfo-l@lists.directionsmag.comSubject: [MI-L] Dynamic expressions in select clauses Hi, I have been trying unsuccessfully to pass a dynamic _expression_ into a select clause in MapBasic. I thought it would be straitforward but somehow it is trickier than I expected. Here is what I did First I retrieved column number n in MyTable from a list in a dialog box (works fine). I would then like to select that column from the table. I wrote the following code: Dim selColumnId as integer Dim selColumnName as String selColumnId = selColumnName = ColumnInfo(MyTable,"col"+selColumnId,COL_INFO_NAME) select selColumnName from MyTable This gives me a single column filled with the String . Any idea how I should proceed instead? Thanks, Francois Blanc ___ MapInfo-L mailing list MapInfo-L@lists.directionsmag.com http://www.directionsmag.com/mailman/listinfo/mapinfo-l
