I'm messing around with DataSnap in Delphi XE2. I have the pre-generated ServerMethods1 class with EchoString and ReverseString. Those work nicely. However, I've added two more simple methods that return simple types and the generated web page of server methods does not include these new...

I've read and experimented a lot with JSON and Delphi. I know how JSON goes to Delphi objects and back through marshaling. The problem I have is that I need to be the consumer of a REST application that wasn't written in Delphi, yet returns JSON objects. I would very much like to work with...

I have many in-house programs which read the currently-logged-in Novell user name to see if they have the necessary permissions to run in-house programs. If the username is empty or [Public], I know they are not logged in to the server and I can abort my programs before they even start. But...

The Delphi help talks about the possibility of overriding the resulting SQL statments that TDataSetProviders use when resolving changes to the back-end database. So, what I have is TSQLDataSet that is a join between two tables. HOWEVER, the query that specifies the join ALSO has a parameter in...

At design-time, TClientDataSet can be right-clicked to select the Assign Local Data... command, which populates it with rows from another dataset. I have not been able to find the equivalent run-time procedure that does the same thing. Note that I am not trying to CLONE a dataset or a cursor...

This is the answer to thread102-1596096 . The problem was Microsoft Security Essentials. Once we added my executable as a process exception, my program launched quickly (as before) and didn't lock any files on the network. GIS Programmer City of Orem, UT http://gis.orem.org

I have a user that is on Windows 7, 64-bit, and is running my 32-bit application written in Delphi 2010. I am using the ExtractIconEx shell command to extract the icons of programs out on a Netware server. For all other 64-bit clients (Vista and 7), this works as expected. On his machine...

For a few versions of Delphi, I've been able to move rich text format code into Word using the following code, where ocxWordDoc is a TWordComponent on the form: var sRTF: String; lRTFFormat, hGlobal: THandle; lpString: Pointer; begin {...} sRTF := qryComments.FieldByName( 'DPCOMMENT'...

Fellow programmers, I have a design issue that I need your help with. I have this project I've been working on for the past few months. It's done. One of the units in that project is full of objects that handle all of the business logic. The objects don't connect to ANY forms, but they do...

I have a very simple procedure which has worked for the last few versions of Delphi (2007, 2006, 2005, and 7). All it does is grab the user name of whoever is logged into the Novell Network on that computer. The sample was pretty much taken off the Novell web site (which is outdated, but the...

Hello, Delphi experts! I am working on an app where I display financial categories, how much money was in to start, how much is left, and what percentage is gone. I plan to do this with a TListView in vsReport style. It would be cool if I could replace the column of percentages with a...

In my organization, when a user inserts a memory stick into a computer running Windows, Windows will often give it a drive letter that's already in use by a Novell network drive mapping. For instance, the stick will get the drive letter F:, though F: may already point somewhere. Consequently...

I have the source code for two Win32 VCL applications. That means I've got class names, Captions, and install locations for both executables. A button in each program opens the other. If the other program is already open, it should show it (bring it to the front). If the other program is...

I have designed a COM Server on paper. It will create, edit, and delete object rows in a database. We access our AS/400 databases using BDE. So, what's my best strategy? Should one DataModule be created for the COM library? When would I create and free it? If I set up my objects with...

Is there a function I can call which will return a Boolean indicating if the given parameter is an SQL keyword? Something like: if IsSQLKeyword( 'SELECT' ) then ... "Roj" GIS Programmer City of Orem, UT http://gis.orem.org

Hello, folks! Here's my dilemma: I've got a program I need to write which takes pictures and stores and prints them. The program needs to control the taking of the picture, and get the picture into memory so I can do what I want with it. Does anyone know of some camera/Delphi API combo that...

I am helping a neighbor with their computer. Here are the specs I jotted down: HP Pavilion 7955 Pentium 4 1.5 GHz 40 GB Fujitsu MPG3409A Hard Drive 256 MB RAM Award Medallion BIOS 6.0 BIOS, Revision 3.05 08/28/2001 When their computer starts up, I get the following error message: DISK BOOT...

I have a program that, ideally, updates its local databases with the click of a button. First, it shuts down all of the tables throughout the program, which are all in the data module. But even with the tables closed, Windows complains that the files are in use. I have opened all the forms in...

Question: Is the Windows.CopyFile method asynchronous? Here's why I'm asking: I copy a file from the network to the users's hard drive. It's a DLL. I then copy another DLL from the network to the hard drive and then call RegisterComServer on it. I get an error message that a dependency file...

I've read in other forums about the WindowMenu property of the TActionMainMenuBar class. It appears that it shipped incorrectly in Delphi 7, but was later fixed. I am working with Delphi 2006 and the property is not persisting very well. I've checked the .dfm and the property is correctly...
