• Visual C# There is no row at position 447: Cannot fill in a DataTable

  I have a DataTable which is filled with rows from a data stream. I Add a row each time a new complete set of field values becomes available. There are 6 fields in rows: three float, one int, one DateTime and one string (rather short, about 4 bytes). After I streamlined my code to eliminate massive losses of data now the process is working fast. All of a sudden I get an error message: There is no row at position 468. I put a Console.WriteLine statement in the routine which handles filling the rows (individually, one by one). Row 469 was created and then the message appeared. In fact when I repeat the runs it breaks down at slighly different rows at each run. Also I have a button which I press. It creates a socket, send a request ...Show All

• Windows Forms Dialog buttons cut off when different monitor is used and resolution lowered.

  I've created dialogs with buttons on them (using Visual Studio 2005 designer) on my machine and when I change the resolution to 800x600 all is fine. Everything shows up as it should.

• Windows Forms How to set and check Low Battery Alarm level and settings through software?

  I am trying to develop a battery test. One part of it will set the low battery alarm to 75% and verify that it triggered, then reset it to the original value. I have looked in many places and cannot seem to find it. However, I know windows is doing this somehow through their Power Options GUI in Control Panel. Anyone care to shed some light on this issue There is ULONG BatteryLevel, which is the percentage level for the alert. BatteryLevel is inside struct SYSTEM_POWER_LEVEL. SystemPowerLevel[0] is for critical battery and [1] is for Low battery alarm. SYSTEM_POWER_LEVEL is inside GLOBAL_USER_POWER_POLICY, which is inside GLOBAL_POWER_POLICY. Use GetCurrentPowerPolicies to read current values. U ...Show All

• .NET Development How do I specify paramaters from my SqlDataAdapter.Update method?

  Hello, I have some code that takes the data from my local machine and then sends it across the network to an SQL server 7.0 backend. Here is my code: myDS.Tables("tblName").Rows.Add(myDataRow) mySQLDataAdapter.Update(myDS, "tblName") The problem that I am facing is when the second line runs, it adds to the data that is already in SQL server 7.0. What I want it to do is update the data on the network where the ID from the local machine is the same as the ID in the data on the network server. Is there a way to specify logic in the SQLDataAdapter.Update as such... mySQLDataAdapter.Update(myDS where id = id, "tblName") Thanks in advance. Hi, the pr ...Show All
