• Smart Device Development IO.Ports.SerialPort - issue with .BytesToRead and DataReceived Event

  Hi Folkes! I'm currently developing an infrared IR-communication software for PocketPC's with Windows Mobile 2003 SE and Windows Mobile 5.0 The communication is based on:    PocketPC virtual serial-port --> IR    and    IR --> Device serial-port. I wrote a communication-library for windows first, which worked perfectly with a real serial conncetion (no use or IR). The same code should work for the virtual serial-port and IR, since it's only a simple IR serial-bridge. Here comes the issue: It's possible to write data from the PocketPC to the device with .Write() It's possible to read data from the device with .Read() and similar. BUT: it's not possible to dertermine how may b ...Show All

• Visual C# C# and Outlook Email

  I want to open an outlook email message in my c# windows form, and I want to know if there's any sort of outlook event that I can use to tell my code if and when the email is sent, so I can then do other things that need to be done if the email is sent (like log it in a database that it's been sent).

• Windows Search Technologies Why would anyone want to install WDS 3 instead of 2.6.x?

  Is it just me or does WDS 3 just seem broken I am trying to understand why I should install WDS 3 when it seems that many features I use each day have been removed. Examples include requiring an add-in to search UNCs, no Group Policy support, no PDF iFilter. Another problem is many of the iFilters I currently use don't work with WDS 3 like the old PDF iFilter. Does this mean that Search in Vista is just as broken Someone indicated that there was a whitepaper or document explaining how to chose the version to install. Does this document really exist --Greg David, Will we be able to exclude folders again THIS IS COMPULSORY! When you have 8 years of email and are registered to 30+ li ...Show All

• .NET Development Computed Columns in TableAdapters / found work-around

  Hello, I'm very frustrated with the TableAdapter created by the dataset designer in Visual Studio 2005. Here's my problem: My select statement is just a select * from X. Some of the columns are computed columns, and should not be included in the update or insert commands. However, they are. I can't seem to get it to not include these columns in the update and insert commands without removing them altogther. This problem did not exist in 2003. Any advice Thanks, Bryce Hi, If I am not misunderstood your question then what you want to do is auto update to database using dataset. If this is the requirement you can update the insert and update statements of adapter so that whenever dataset ...Show All

• Visual C++ Visual Studio features - gone in later versions

  I'm trying to figure how to do certain things in a later version of Studio that I could do in VS6 but don't work anymore. Such as (a) dismiss the compilation output window just by hitting ESC, and (b) identifying the exact path to a given source file. I switched from 6 to .NET a couple of years ago, and have regretted not knowing how to make .NET behave like 6 in these particular areas. Aha. I got it. The build output window got "pinned". Unpinned, life is good again. Boy is that stupid of me. Anyway, I'm good now. Thanks - ...Show All

• .NET Development How to randomly delete 1 row from a DB ?

  Hello, I'm writing a program with the help of VB 2005 Express. It is connected to a DB using SQL Express Server 2005. In my program I want to randomly delete some rows from the table. I use the VB code: Dim WhichOne As Integer = rnd() * 40 (where 40 is the amount of entries in the DB) Dim DeleteQuery As String = "DELETE * FROM Table LIMIT '" & WhichToDelete & "', '1'" Dim DeleteCommand As New SqlCommand(DeleteQuery, myConnection) DeleteCommand.ExecuteNonQuery() If for example WhichOne = 17, it should execute an SQL query: DELETE * FROM Table LIMIT '17', '1' Which imo should delete the 17th entry in the table. Now I get an error on the execution of the SQL command, but what is it that I'm doing wrong ...Show All

• Visual Basic tables

  Hi there Until recently I used RapidQ basic to produce my number crunching applications. The move to VB2005 was dead easy. There is however one feature / keyword I badly miss. In rapidq there is the StringGrid control, where you can print, for example, the values from an array on a GUI. Once you set-up the stringgrid, writing into it is a simple as: stringgrid.cell(xy) = str$(value) By comparison, generating a table in VB2005 is very difficult. Any suggestions will be appreciated. Hey Nog, Note that this is a historic thread and topic... the thread has almost 39,000 views.

• .NET Development DataTables and SQLDataAdapter events can trigger eachother causing additional hits to the Database

  I've noticed when doing inserts and updates to a SQL database from a DataTable, the SQLDataAdapter will AcceptChangesDuringUpdate and AcceptChangesDuringFill. This is a great feature, except when the data values come from the database such as a Primary key for a new row or default values when no value was specified by the end user, then this causes another RowChanged event to fire and the Update back to the database is called because the RowState is set to Modified when the DataTable Row is updated with the new values from SQL. I'd like to be able to halt notifications on a DataTable under certain circumstances such as while I'm executing an SQLDataAdapter.Fill(dt) or on some other unknown occasion... Is this currently possible or wi ...Show All
