c# - DataGridView - Click on Image in Cell and show new Form with full size image -


all: newbie working datagridview1 bound sql server db table via visual studio data sources function. have filled datagrid columns in table, including column containing blobbed image, shows correctly in datagridview slice of image. user able click on datagridview1 cell contains slice of image , launch new form specific image background of (or @ least fill picturebox on same form), can't seem able reference specific image in cell clicked... have tried, unsuccessfully, using "datagridviewimagecolumn" like:

    imagecolumn = new datagridviewimagecolumn();     imagecolumn.image = this.imagedatagridviewimagecolumn.image;     frmpic.backgroundimage = imagecolumn.image;

can advise correct code use reference specific image?

i think can use datagridview_cellclick event handler,

so can :

 private void datagridview_cellclick(object sender, datagridviewcelleventargs e)  {      // set index pic column, assume pic in column 0     int index = 0;      // check clicked cell right cell     // , every thing okay.      if (datagridview.currentcell.columnindex.equals(index) && e.rowindex != -1)     if (datagridview.currentcell != null && datagridview.currentcell.value != null)     {         // cast image         bitmap img = (bitmap)datagridview.currentcell.value;          // load image data in memory stream         memorystream ms = new memorystream();         img.save(ms, imageformat.jpeg);          // can open image in picbox memory stream.         // if want open pic in other form, need pass memory          // stream form, e.g., in constructor.          // open other form         newform obj = new newform(ms)     }  }

in newform constructor use memory stream load image in pic box.

 public newform(memorystream ms)  {     picbox.image = image.fromstream(ms);  }

i hope helps you, luck !

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
