• Software Development for Windows Vista Inconsistent File System Enumeration with FindFirstFile / FineNextFile

  I'm working to get a commercial application to run on Vista. Among the many broken things, the first one I encounter is a crash due to a stack overflow due to a recursive function that goes bad. The app enumerates files in various places using FindFirstFile | FineNextFile in a recursive function (C++). I'm using retail Vista Ultimate with VS 2005 sp1 plus the VS Vista update beta. What I see in the debugger is that when I start out enumerating drive "c:", I come to the "Documents and Settings" folder and recurse into it. When I get to "c:\Documents and Settings\All Users\Application Data", FindNextFile then returns "Application Data" over and over again and I recurse into "Application Data&qu ...Show All

• .NET Development EXE (client PC) don’t show null values

  I'm developing a c#.net application using AdabasD ODBC. I've installed the exe in 4 PCs and is all right ... except in one that doesn’t obtain rows from row tables that contains 1 or more null values. Any idea THANKS !! I suspect you are using some sort of a DSN (user/system/file) to make the ODBC connection. It’s possible that the DSN on the problematic machine is different from the others. For instance the SQL Server driver has a setting ANSI_NULLS that configures that exact behavior. I’m not familiar with the Adabas driver but it may have a similar setting.

• .NET Development socket receive question

  Hi, I need to build a client-server tcp socket program, the client needs to send some commands to the server and needs to wait there for the response from the server. I am thinking of using sendto&receivefrom to do this synchronized call. But the server side will send some data to client irregularly, so I need to have something listerning, I think I must use BeginReceive to receive the data from this socket. So the problem is how to mix synchronize and asynchronize during receiving. I am a socket newbie and am confused with this case. Would you please to clarify it to me and give me some hints how to implement it Thanks a lot. Thanks, Frank & Rizwan, After reading your posts, I got ...Show All

• Windows Forms Nested events

  I have an win forms application that contains three user controls. There is a one to many relation between control B and A, a one to many relation between control B and C, and a one to many relation between control C and the form. Control A contains an event that needs to be raised up to the form. To accomplish this, I created an event in both control B and C. For example, There are 2 "C" controls with 7 "B" controls, and 0 to many "A" controls within B. All controls are being dynamically created. Controls A, B, and C are instantiated at run time, so my event handlers all wire up to a single delegate b_onchange, rather than b1_onchange, b2_onchange etc.. What appears to happen in this case, is when the event ...Show All

• Software Development for Windows Vista Inheritance from custom activity

  I wish to make a custom activity that inherits from another custom activity. My first activity "Activity1" inherits from System.Workflow.ComponentModel.Activity. My second activity "Activity2" should inherit from "Activity1". In the designer I attempt to change the "base class" attribute of "Activity2", but for some reason I cannot choose "Activity1" to be my base class. In other words, the <Current project> folder is empty and I can only choose from Referenced Assemblies. If I put "Activity1" in another Workflow Activity Library and reference that library from my other project it seems to work just fine. I do not however understand why I can't inherit from activities in my current project, and I would be very happy if ...Show All

• Windows Forms The DateTimePicker is Ridiculous!

  Why doesn't the DTP allow you to select a Date AND a Time at the same time Instead, (from what I see) you have to create 2 DTP controls: One to select the date and another to select the time of day. Why can't they be on the same popup similar to how MS Access would let you select both Please somebody tell me I'm wrong and just missing something. I've been Googling around to try and find a custom one, but they are few and far between. Aren't there other people with this problem I thought this was basic stuff... If anyone knows of any custom controls that do this, I'd be greatful if you let me know. Thanks! Hello All. Igore99: You can have the DateTimePicker control select both the dat ...Show All
