<p>I used to use project references, but it all seems to go bad, when as you say, you have many projects referencing it.</p>
<p>I now compile to a DLL, and set the CopyLocal property for the DLL reference to false after the first build (otherwise I find it can override s... | 6,268 |
<p>As stated in the title, i'm looking for an XML schema (XSD-file) for the Glade markup language?</p>
<p>Wikipedia states that <strong>Glade</strong> is a schema based markup language (<a href="http://en.wikipedia.org/wiki/List_of_XML_Schemas#Graphical_User_Interfaces" rel="nofollow noreferrer">list of schemas at wik... | <p>There's nothing that will explicitly tie down the glade to an particular schema since it's all run-time based.</p>
<p>You may find the .defs files generated by PyGTK useful. If you really need an XSD file, you should be able to create one from these files.</p>
<p><a href="http://svn.gnome.org/viewvc/pygtk/trunk/g... | <p>Thx, this is a first start. I assume there is no document that is more explicit that this DTD? This DTD only specyfies what (global) tags can be used. Especially for the tag <widget> i would like a have constraints on the attribute "class" (as supported by XSD). The XSD should cover that there are only certain... | 9,061 |
<p>I have an SSIS package that exports data to a couple of Excel files for transfer to a third party. To get this to run as a scheduled job on a 64-bit server I understand that I need to set the step as a CmdExec type and call the 32-bit version of DTExec. But I don't seem to be able to get the command right to pass in... | <p>This step-by-step example is for others who might stumble upon this question. This example uses <em>SSIS 2005</em> and uses <em>SQL Server 2005 64-bit edition server</em> to run the job.</p>
<p>The answer here concentrates only on fixing the error message mentioned in the question. The example will demonstrate the ... | <p>I kinda did what Dr Zim did but I copied the DTExec file <code>C:\Program Files (x86)\Microsoft SQL Server\90\DTS\Binn\DTExec.exe</code> to <code>C:\Program Files\Microsoft SQL Server\90\DTS\Binn\</code> folder but named the 32 bit one to DTExec32.exe</p>
<p>then I was able to run my SSIS script through a stored pr... | 4,160 |
<p>Why is it that if I execute a gcode command that causes the stepper motor to turn in reverse (any negative move on the X axis), after the step it will emit a high pitched whine until it gets another command to rotate in its forward direction?</p>
<p>Executing multiple reverse commands will cause the tone to vary in... | <p>When idle, the stepper is stationary, no rotation.</p>
<p>Normal standard electric motors will start spinning as soon as you apply power to them. However, steppers only rotate when a magnetic field is applied<sup>1)</sup>:</p>

<p>How do you schedule a Windows Mobile application to periodically start up to perform some background processing. For example, assume I'm writing an email client and want to check for email every hour, regardless of whether my app is running at the time.</p>

<p><code>CeRunAppAtTime( appname, time )</code></p>
<p>that isn't the exact signature, there is also <code>CeRunAppAtEvent</code>, they should both be in the MSDN docs (but linking is useless the way MSDN urls always change)</p>
