Try `buttonname.BackgroundImageLayout = ImageLayout.Stretch;` or change this property in designer.

My solution was to use an ImageList control.  You can define the size the images are to be displayed (e.g. I set the ImgageList ImageSize property to 16x16) and then set the button.ImageList and ImageIndex properties instead of the Image property.

I think if you use the **Paint event** of the Button you can draw any image in any size that you want. if it isn&#39;t possible to re-size the image you can do that in this way.

If you have the Image with size 16*16 then set these Button properties at design time.
   1) TextImageRelation - ImageBeforeText
   2) TextAlign - MiddleRight
   3) ImageAlign - MiddleLeft
   4) Set the 

If you are using DevExpress Simple Button, you should set BackgroundImageLayout = ImageLayout.Zoom and set backcolor of button to **Transparent** (from **Appereance-&gt;Backcolor**)

    ImageList imageList = new ImageList();
    imageList.ImageSize = new Size(30, 30); // specify size you want

I have 3 tables: User, Community, community_members (for relationship many2many of users and community). 

I create this tables using Flask-SQLAlchemy:

    community_members = db.Table(&#39;community_members&#39;,
                    db.Column(&#39;user_id&#39;, db.Integer, db.ForeignKey(&#39;user.id&#39;)),
                    db.Column(&#39;community_id&#39;, db.Integer, db.ForeignKey(&#39;community.id&#39;)),
                    )


    class Community(db.Model):
        __tablename__ = &#39;community&#39;
    
        id = db.Column(db.Integer, primary_key=True)
        name = db.Column(db.String(100), nullable=False, unique=True)
        members = db.relationship(User, secondary=community_members,
                                backref=db.backref(&#39;community_members&#39;, lazy=&#39;dynamic&#39;))


Now I want add additional field to community_members like this:

    community_members = db.Table(&#39;community_members&#39;,
                    db.Column(&#39;id&#39;, db.Integer, primary_key=True),
                    db.Column(&#39;user_id&#39;, db.Integer, db.ForeignKey(&#39;user.id&#39;)),
                    db.Column(&#39;community_id&#39;, db.Integer, db.ForeignKey(&#39;community.id&#39;)),
                    db.Column(&#39;time_create&#39;, db.DateTime, nullable=False, default=func.now()),
                    )


And now in python shell I can do this:

create community:

    &gt; c = Community()
    &gt; c.name = &#39;c1&#39;
    &gt; db.session.add(c)
    &gt; db.session.commit()

add members to community:

    &gt; u1 = User.query.get(1)
    &gt; u2 = User.query.get(2)
    &gt; c.members.append(u1)
    &gt; c.members.append(u2)
    &gt; db.session.commit()

    &gt; c.members
    [&lt;User 1&gt;, &lt;User 2&gt;]


Ok, this works.

But how now I can get time_create of community_members table?

Hi I don&#39;t want an image for my submit button so I have gone with the default submit button but I want to edit its width and height. How do I do that?

Thanks!

How to edit the size of the submit button on a form?

I have a button and I want image (.ico file) and text to exist on it. My problem is that I want button&#39;s height to be small, but I can&#39;t manage to &quot;shrink&quot; the image as much as I want to. The result is to have a piece of image visible on the button and not the hole image. At the image property the image size is fixed (48x48) and the option is grey so I can&#39;t change it. How can I make this image to be 16x16?

What is the quickest way to read a text file into a string variable?

I know that this is Linq:

    var _Results = from item in _List
                    where item.Value == 1
                    select item;

And I know this is Lambda:

    var _Results = _List.Where(x =&gt; x.Value == 1);

&gt; **Editor&#39;s note:** the above is not merely Lambda, it is Linq using the &quot;Method
&gt; Syntax&quot; whose predicate is a Lambda. To be clear, both of the above
&gt; samples are Linq (my original post was incorrect, but I left the error
&gt; to illustrate the confusion prompting the question).

But is Linq a subset of Lambda or what?

Why are there two seemingly identical techs?

Is there a technical reason to choose one over the other?

Is it Linq or Lambda?

Writing an infinite loop is simple:

    while(true){
        //add whatever break condition here
    }

But this will trash the CPU performance. This execution thread will take as much as possible from CPU&#39;s power.

What is the best way to lower the impact on CPU?
Adding some `Thread.Sleep(n)` should do the trick, but setting a high timeout value for `Sleep()` method may indicate an unresponsive application to the operating system.

Let&#39;s say I need to perform a task each minute or so in a console app.
I need to keep `Main()` running in an &quot;infinite loop&quot; while a timer will fire the event that will do the job. I would like to keep `Main()` with the lowest impact on CPU.

What methods do you suggest. `Sleep()` can be ok, but as I already mentioned, this might indicate an unresponsive thread to the operating system.

**LATER EDIT:**

I want to explain better what I am looking for:

1. I need a console app not Windows service. Console apps can simulate the Windows services on Windows Mobile 6.x systems with Compact Framework.

2. I need a way to keep the app alive as long as the Windows Mobile device is running.

3. We all know that the console app runs as long as its static Main() function runs, so I need a way to prevent Main() function exit.

4. In special situations (like: updating the app), I need to request the app to stop, so I need to infinitely loop and test for some exit condition. For example, this is why `Console.ReadLine()` is no use for me. There is no exit condition check.

5. Regarding the above, I still want Main() function as resource friendly as possible. Let asside the fingerprint of the function that checks for the exit condition.

How might I remove characters from a string? For example: `&quot;My name @is ,Wan.;&#39;; Wan&quot;`.

I would like to remove the characters `&#39;@&#39;, &#39;,&#39;, &#39;.&#39;, &#39;;&#39;, &#39;\&#39;&#39;` from that string so that it becomes `&quot;My name is Wan Wan&quot;`

I have a problem with an MVC 3 application that is using the new .NET 4 System.Runtime.Caching MemoryCache. I notice that after a seemingly unpredictable time, it stops caching stuff, and acts like it&#39;s empty. Consider this bit of code that I took straight from a test View in ASP.NET MVC:

    MemoryCache.Default.Set(&quot;myname&quot;,&quot;fred&quot;, new CacheItemPolicy() { SlidingExpiration = new TimeSpan(0,5,0) });
    Response.Write(MemoryCache.Default[&quot;myname&quot;]);

When it&#39;s working, predictably &quot;fred&quot; gets printed. However, when the problem starts to occur, despite the `Set()`, the value of `MemoryCache.Default[&quot;myname&quot;]` is null. I can prove this by setting a breakpoint on the `Response.Write()` line and directly setting and reading from the cache using the Immediate Window - It just won&#39;t set it and stays null! The only way to get it working again then is to cause an AppDomain recycle.

Intriguingly I can provoke the problem into occurring when the app is working normally by breaking on the `Response.Write()` line and running `MemoryCache.Default.Dispose()`. After that, MemoryCache.Default is not null itself (why is this?), but won&#39;t save anything set on it. It doesn&#39;t cause any errors, but just won&#39;t save anything. 

Can anybody verify this and explain? As I believe I have discovered, when the app stops working on its own, *something* is Disposing `MemoryCache.Default`, but it&#39;s not me!

---

**UPDATE**

Well, I&#39;m sick of this prob now! CLRProfiler doesn&#39;t seem to work with MVC 3. SciTech&#39;s CLR tool was good - so was RedGate ANTS. But all they told me was that the MemoryCache object is being disposed by *something*! I also proved (via a timestamp print) that a PartialView on my page that should be cached (specified by OutputCacheAttribute) stops being cached after a few minutes - it starts refreshing with every call to the page. Just to clarify the environment, I am running directly on the IIS 7.5 server on my development workstation running Win 7 Ultimate. The memory tools mentioned above suggest I am only using about 9mb of memory in terms of objects in play.

In desperation I have changed my caching code to first search for an ambient HttpContext to hook onto and use its Caching functionality, if one&#39;s available. Early tests show this is reliable, but it feels like a nasty hack.

Am getting the feeling that MemoryCache and OutputCache aren&#39;t warranted to work with MVC 3...
