hi all!! I am on a project that need show the fields that have a DB, but in a APP of Desktop I haven't problem to do this. Now in ASP I don't know do that. In a simple way to show what I do, I drop yours this code, that try to fill a dataset to show then in a crystalR. DataSet ds = new DataSet(); sqlConn = ConnectionPool.GetConnection(); SqlTransaction sqlTrans = sqlConn.BeginTransaction(); ds = SqlHelper.ExecuteDataset(CommandType.StoredProcedu re,"DP_GetAllEmp",sqlTrans); sqlTrans.Commit(); sqlTrans = null; ConnectionPool.ReleaseConnection(sqlConn); CrystalReport1 cr1 = new CrystalReport1(); cr1.SetDataSource(ds); CrystalReportViewer1.ReportSource = cr1; //this is the problem //in this place exploit, and said me that the report data source isn't valid if everybody have any idea, please say me

be more explicit, and tell my if you need still this answer yet regards

yes as you know, all word that we say, more or less, have a average in a frequency scale, but not wory, indeed I star now a project for do many things using this topic "sound", when I finish this a post that... regards for all:-D

greetings for all, I am very instered in learn how work with sound in c#... for instance load a music file, see the frequency of that, if any one have any idea or better have a project as example, please tell my, regards my;)

hi, in the last reply, I show you how you can select the rows in a listbox, but how you no tell my any more, I expect that you stand all.... regards sno-1:laugh:

sorry for the long time, but I can'nt seat before my pc in some many hours, ok your question is simple the best mode to give you the answer is with a example.... if you have a listbox and in them properties selection mode you put "MultiSimple", and you do a correct add of the elements to show in run time, you selected the item that you need to save in your DB maybe using that int [] a; int p=0; p=this.listBox1 .SelectedIndices.Count ; a=new int[p]; for (int i = 0;i < p;i++) a[i] = this.listBox1 .SelectedIndices [i]; and in the array "a" you have all the position that be selected, the rest i think you know, make a loop wih that and with the class SqlParameter add all this position or the name of the item under this position.... is a plaesure help you, if you have any question tell me ok....:laugh::laugh::laugh:

is very simple only you need keep in a loop for instance this: System .Drawing .Icon nuevo=new Icon (@"D:\MyIconNow.ico"); Random manual=new Random (); int p = manual.Next (2); if (p == 1) base.Icon=nuevo; else base.Icon=null; of course, the loop is'nt the only way too keep that atach in execution, try with delegate... if you wanna know anything write me :laugh::laugh::laugh:

first sorry if I give'nt you a good answer because I dont undertand you a lot, ok this is fact: if you need know the process data of this 4 thread, you can use many tools, such as delegate, create a delegate and add all this function inside this, and then put the delegate on execution, for more explanation look this example, using a ProgressBar... public delegate void ExceutionAsyncronous(); public void function1(){} public void function2(){} public void function3(){} public void RequestTime(ProgressBar som, int value, int max) { som.Increment(value++,max); } inside your function put this method "RequestTime" in a way that the increment always keeping inside a correct interval, an then ... ExceutionAsyncronous ob = new ExceutionAsyncronous(function1); ob+=new ExceutionAsyncronous(function2); ob+=new ExceutionAsyncronous(function3); ob(); Remember that this explanation only want give you a Idea, ok if you need know anything else, please write me ok :-D:-D:-D

ok this is the fact, first you can do that for a very simple way, for instance: System .Drawing .Icon nuevo=new Icon (@"D:\MyIconDirection.ico"); Random manual=new Random (); int p = manual.Next (2); if (p == 1) base.Icon=nuevo; else base.Icon=null; and I dont know, you can use for repeat that many times, a timer, thread, delegate to do that ashyncrons:-D, you choose... for any question or another think write me... :-D:-D:-D

remember that the listbox in this powerfull lenguage c#, have many components that you can use in your project, for intance, only you need load the information in a datatable for example, and then tell to the listbox, and you can use too a combobox, the properties datasource that you load from a datatable: public void LoadDatatable(ref system.data.datatable some) { cmd = new SqlCommand("yourStoredProcedureOrStatement",con); cmd.CommandType = CommandType.StoredProcedure; try { adapt = new SqlDataAdapter(cmd); adapt.Fill(some); } catch(Exception ex){throw ex;} finally { con.Close(); } } system.data.datatable p=new system.data.datatable(); LoadDatatable(ref p); and after all this, only rest that you tell to the combobox or listbox, anyone that the properties DataSource = p; and the way too show the thinks that was load: ListBox.DataSource = p; ListBox.DisplayMember = "The name of the thinks that you like show"; ListBox.ValueMember = "A id, if exist, only to give more handle to this control"; ok I hope that this thinks help you.... one think: Forgive me by my English ok, because in my contry this idioms i'snt speak a lot.... if you wanna another answer o whatever please write me :laugh::laugh::laugh: e-mail:joelintel@gmail.com
