Hi All
I want to set/control a selection range on a System.Windows.Forms.TrackBar.
I think that can be accomplished by setting TBS_ENABLESELRANGE, but I can't find a property or method to set the value. Can someone tell me how to configure the TrackBar to select/display a range? If so, how do you read the range back?
Thanks
Robert Ernst

Hi
I would like to trace my application and put all messages in a text file.
I use
Trace.TraceError("");
Trace.TraceInformation("");
Trace.TraceWarning("");
methods and when TraceSwitch level is set to for instance Error all messages are put in a file?
Why?
I thought when I set TraceSwitch (ts) to Error only TraceError messages would be sent.
I would like to change only trace level and certain messages should autmatically be put in a file.
Should I use Trace.WriteIf(ts.TraceError == true,"...");
What for if TraceError, TraceWarning etc.???

I'm looking for a good book or other resource that describes best practices for separating an application into presentation, business logic and data access layers. I am particularly interested in best practices for designing the communications between the layers and the structure of the application that allows data to be retrieved from the data source via the data access layer then passed to the presentation layer through the business layer and then back through the business layer to the data access layer. Does anybody have any recommendations?

Your service is running under the Local System account, but in your connection string your specifying Trusted Connection. You can't do that since the Local System account is not trsuted by the SQL Server, and can't be. Remove the Trusted Connection part of your connection string, but still supply an SQL username and password to use. DO NOT USE THE 'SA' ACCOUNT! Create a seperate account to be used by the service for this database.

Remove the Integrated Security junk. This is what's causing your "trusted connection".
Provider=sqloledb;Data Source=software-14;Initial Catalog=company071;User Id=terminalassword=abc;

thaksn again
but dear this time it gives this exception
Login failed for user 'terminal'. Reason: Not associated with a trusted SQL Server connection.
my connection string is
"data source = software-12;initial catalog = company071;user id=terminal;passowrd=abc"
hello
|
|
|
|
|
Did you copy/paste this connection string or just type it into this post??
If you're using the SqlConnection object, it should be:
"Data Source=software-12;Initial Catalog=company071;User Id=terminal;Password=abc"
This will work so long as you've created a user id terminal and assigned it the appropriate permissions to the company071 database. This means, at a minimum, giving that user db_datareader and db_datawriter roles in your database.
Also, when you created the user, did you turn on SQL Server authentication for it?

No i just typed this string here , my this service works fine of i provide my local system sql server in connection string,even i give trusted connection = true in the case of local sql server ...so connection string is working fine .

hello

The default database is not master. It should be Company071.
Other than that, I can't see what you did wrong. Either there's something you're not telling me, or there something you are telling me that's not been verified as being true.

I'm looking for a way to persist (or at least serialise) all the properties of a Control, in particular a DataGridView. I would like to emulate the MS Access feature, where if I change, for instance, a column width at run time, the grid retains the new width for future sessions.
I could hard-code only certain properties, such as column width, but I'm busy setting up a prototype project that allows me to play with many properties at runtime and immediately see the effects of my changes. I would like to preserve configurations I prefer for use in production scenarios.
I could do this with reflection, but that's a bit more involved than I want to get right now.

You have to create at least one separate application pool for your .NET 2.0 applications. An application pool uses a single (pool of) worker processes, W3WP.EXE. A process can only load one version of the .NET CLR in its lifetime. If they share a pool, whichever version of the framework loads first will be the only version running in that pool. This can cause .NET 2.0 applications to fail if they end up running on 1.1 or vice versa.

Hi all!
I'm writing a program where I need to make some drawings over previously created
in-memory Metafile. The very first drawing succeeds but next time I'm trying to
call Graphics.FromImage on same metafile object OutOfMemoryException is being thrown.
Can anyone say me, what exactly happens?
Thanks a lot.
P.S. Please excuse me for my poor English.
<br />
Metafile meta = null;<br />
MemoryStream mstream = new MemoryStream();<br />
<br />
using (Graphics gr = CreateGraphics())<br />
{<br />
IntPtr attribDc = gr.GetHdc();<br />
meta = new Metafile(mstream, attribDc);<br />
gr.ReleaseHdc(attribDc);<br />
}<br />
using (Graphics gr = Graphics.FromImage(meta)) <br />
{<br />
m_Visualizer.DrawTemplateMnemo(m_Template, gr);<br />
}<br />
using (Graphics gr = Graphics.FromImage(meta))
{<br />
m_Visualizer.DrawTemplateMnemo(m_Template, gr);<br />
}<br />
