i have a asp.net mvc website which runs a number of queries for each page. Should i open up a single connection or open and close a connection on each query?
MethodInfo mi = typeof(NotifyIcon).GetMethod("ShowContextMenu", BindingFlags.Instance | BindingFlags.NonPublic);
mi.Invoke(notify, null);
This throws the following exception:
{"Exception has been thrown by the target of an invocation."}
With the following inner exception:
"Cross-thread operation not valid: Control '' accessed from a thread other than the thread it was created on."
If I comment out a line of code that sets the images for the context menu entries then it stops throwing the exception.
Any ideas?
Lets assume that a rule (or rule of thumb, anyway), has been imposed in my coding environment that any method on a class that doesn't use, modify, or otherwise need any instance variables to do its work, be made static. Is there any inherent compile time, runtime, or any other disadvantage to doing this?
Let's say I want make some of my sources publicly available via my blog or other web location.
How do I properly indicate what Open Source license I've applied to the sources? For instance, with the MIT License or The Code Project Open License, should I put something at he top of the source files or should I have something on the web page, or both?
Is there any way to copy a really large file (from one server to another) in Powershell AND display it's progress?
There are solutions out there to use Write-Progress in conjunction with looping to copy many files and display progress. However I can't seem to find anything that would show progress of a single file.
Any thoughts?
I have a long list of integers, and i need to reduce this down to a single integer. The integer list can be anywhere from 0 to 300 ints long (about). I need to be able to encode/decode.
Is there a better option than a lookup table?
I've banging my head for hours, it seems simple enough, but here goes:
I'd like to create a view using multiple select statements that outputs a Single record-set
Example:
CREATE VIEW dbo.TestDB
AS
SELECT X AS 'First'
FROM The_Table
WHERE The_Value = 'y'
SELECT X AS 'Second'
FROM The_Table
WHERE The_Value = 'z'
i wanted to output the following recordset:
Column_1 | Column_2
'First' 'Second'
any help would be greatly appreciated!
-Thanks.
I dont see any direct mention on using multiple slugs (or any behavior for that matter) for single model. Is there a way to use the sluggable behavior to generate two separate slugs for a model?
For example i need to generate two slugs for every record a product_id consisting of a slugified company name and sku and a distributor_id consisting of a different slugified company name.
Obviously i could write this myself fairly easily, im just wondering if this can be done quickly with Sluggable.
Hey !
I am making an application which is a user interface to access 2 types of databases - SQLite and MSSQL server.
The thing is, SQLite doesnt need to be "installed" since its just a flatfile database, but on the other hand, SQLserver (Express/normal) need to be installed before use. My Question is simple:
Is there a way by which i can find out if an instance of SQLserver has been installed on the local machine by using a C# program?
Is it possible to tell the Qt MOC that I would like to declare the class and implement it in a single file rather than splitting them up into an .h and .cpp file?
Update
If you were forced to use a single char on a split method, which char would be the most reliable?
Definition of reliable: a split character that is not part of the individual sub strings being split.
Hi
I writing a WCF Service that need transfer large files, so i using streaming, but from the other hand i need to do username specific initializations.
The problem is that getting the username and perform initialization every time is very expensive. If i could turn on session, i could just save initialized data in local variables in the service instance.
Is there a way to turn on both streaming and session in netTcpBinding?
I'd like to know how to get an array rows & columns size. For instance it would be something like this:
int matrix[][] = { { 2, 3 , 4}, { 1, 5, 3 } }
The size of this one would be 2 x 3. How can I calculate this without including other libraries but stdio or stdlib?
In Visual Studio with Resharper I can set the project to background build as I type. A red icon on the status bar appears the instance I code something wrong. Green if all is good. It does this by compiling all the time.
Is there a way to enable this in Eclipse?
We're trying to create a powerpoint slide programmaticaly. We can obtain bullets on a single level, but playing with tabs and line returns doesn't work for nested enumerations.
For now we got :
text 1
subtext1
subtext2
text 2
And what we want is :
text 1
subtext1
subtext2
text 2
Is there a way to control these using C# or VBA?

return r.Single(id).logo.ToArray();

Suppose I want my draggable widget to move differently than just staying under my cursor while being dragged. For instance, having the widget move only in one axis, or have the widget move double the distance between the cursor and the drag starting point. Which method should I override to define this kind of behaviour?
Using prototype, is there a simple method of checking that a group of values match, for example - can this code be refined to a single line or something otherwise more elegant?
var val = '';
var fail = false;
$('form').select('.class').each(function(e){
if(!val){
val = $F(e);
}else{
if(val != $F(e)) fail = true;
}
});
I have a scenario where I need to send a series of data across 2 clients.
The data includes Serialized XML that will contain commands that the other client will need to react to.
I will also need to send images across the wire as I need to provide a chat facility in the form of video/audio chat.
I would like a single communication medium for both, as the number of messages/commands might be a few.
WCF or Sockets?
And how do I convert it to a datetime.datetime instance in python?
