I'm trying to trigger a software that i've installed into the PC under C drive program files but this doesn't work.

• Andr&amp;#233;_Silva Seperating DataSets,DataAdapters stuff from Applications

  Hi, This is probably for most of you a very basic question. My goal is to define in a seperate instance from application all infos related to DataSets and DataAdapters that are needed when connecting to a specific database. Why First, I would like to be able to have in a single instance everything needed when hooking to a SQL Server Express database and in an other everything needed when hooking to a SQL Server CE database. Then, from application, I would like to be able following a few basic configuration steps to choose from one or the other, or even both in specific cases. Second, I want to be able to seperate Database related stuff from application so that I can re-use everything from any other application when needed. ...Show All

• curt2go Passing login information to remote windows file share

  I have looked all over the net for information on how to do this and am still lost. I want to copy files from a remote server that has file sharing enabled, however the login information does not match the local domain. So when I try a File.Copy on the remote file I get a error unless I first launch iexplore to the URL of the site ( \\10.100.1.1 for instance) and then it will allow the user to manually authenticate and after that it works. Is there any way to automate this and pass the login info Anyone Or can someone suggest another forum I could ask at The impersonate stuff won't work in this example as the remote system is on a different domain. It's as simple as logging in via the windows prompt thou ...Show All

• Ido Ran Fill DataSet from Txt, memory doesn't like it

  Hi all, This is my first question. Perhaps anyone can help me with what I'm doing wrong and what I can do about it. I am reading a textfile row-by-row, modelling and analyzing the data. Each row is then put in a DataSet. Afterwards, we will bind the DataSet to a DataGrid and allow the user to view/edit records before it is finally published to a SQL database. Sometimes the amount of records is substantial, so to display the status and keep the GUI responsive this process has been contained in a backgroundworker. Ofcourse not with every processed row the status is updated, but in batches. Say about every time 100 records are processed. All works perfectly fine, with the horrible exception that reading large sourcefiles (+1million rows/200mb ...Show All

• TomJ72 CodeDOM: Runtime Type-Builder

  Hi all, I'm attempting to realize something that maybe is not realizable: a runtime TypeBuilder which produce the same Type used by a component at compile tyme. Shortly, provided I know that compononent X consume a Type TY of which I have a fully comprehensive knowledge, I would make it possible to produce at runtime a Type TZ that is equivalent to TY. Motivation : I could use serialization to made up a prorotype and than pass it, I would avoid this way because the types are defined through an higher level abstraction that I would manage transparently, and, moreover, because I would face a deploy critical issue: how these prototypes should be packaged provided that new types are created very often, by different people, and nobody ...Show All

• TexasDeveloper Error passing parameters to Fillby Query

  Hi, I'll try to keep this succint. I'm using VB into an Access DB with an ODBC connection. I wrote a fillby query that looks exactly like this: SELECT     OrderDate, Notes, ShippingCost, DateReceived, Supplier, PO, UserName, Completed, POTotal FROM         Purchases WHERE     (OrderDate >= [StartDate]) AND (OrderDate <= [EndDate]) (yes, I changed the prefix and suffix because it kept coming up with syntax errors.)
