Hi all, I have a listview control which is binded with gridview columns binded to cell template with static resource. my listview is bounded to a list of class objects as itemssource.i am trying to get all the items using the below code. GridView gridView = lvView.View as GridView; foreach (TicketExceptions item in lvView.Items) { VirtualizingStackPanel vsp = (VirtualizingStackPanel)typeof(ItemsControl).InvokeMember ("_itemsHost", BindingFlags.Instance | BindingFlags.GetField | BindingFlags.NonPublic, null, lvView, null); double scrollHeight = vsp.ScrollOwner.ScrollableHeight; double offset = (scrollHeight * lvView.Items.IndexOf(item)) / lvView.Items.Count; // itemIndex_ is index of the item which we want to show in the middle of the view vsp.SetVerticalOffset(offset); lvView.ScrollIntoView(item); ListViewItem item1 = lvView.ItemContainerGenerator.ContainerFromIndex(lvView.Items.IndexOf(item)) as ListViewItem; // item1 returns null for few items GridViewRowPresenter rowPresenter = GetFrameworkElementByName<GridViewRowPresenter>(item1); foreach (PropertyInfo info in item.GetType().GetProperties()) { for (int col = 0; col < colcount; col++) { if (rowPresenter != null) { ContentPresenter templatedParent = VisualTreeHelper.GetChild(rowPresenter, col) as ContentPresenter; TextBlock block = (TextBlock)gridView.Columns[col].CellTemplate.FindName(info.Name, templatedParent); if (block != null) { } } } } But the ItemContainerGenerator returns null for few items. when i checked, i see that only the items which are in visible in the listview (rather than scrolling) returns object using the above method, but others return null. i am able to see all the items in the listview. How can i get the container of the items without scrolling.

Thanks in advance.:) Regards Anuradha

hi all, i have written a service in vb.net which repeatedly processes messages in the messagequeue. i send a message from messagequeue to a server through a gateway and wait for the response. I am using TCP Client that listens to a port, to send message to the gateway(an application that interacts with the server)and receive response from the server through the gateway. I am able to send and receive message from the gateway. The time taken to send message to the gateway is quick(1 or 2 seconds). but the response i get from the gateway takes a longer time. around 40 seconds. The server part of coding is done by another person and i dont have permissions to that side. How can i receive a faster response? is there anything i can do to improve it or should it be done in the server side?

Thanks in advance.:) Regards Anuradha

hi all, I have a dataset which has four tables. say for eg, Table A, Table B, Table C and Table D. Table A and Table B are related using PK - FK relation.Table B and Table D are related using PK - FK relation. Table A and Table C are related using PK - FK relation. i need to create a xml file based on these relations. i need to have a node which has the related values of all the tables. I tried using a single query to extract values based on inner joins. but that comes as a single table and the nodes are repeated. or can anybody suggest me how to group two tables into a single node in xml. i can do all this by manually creating a xml file from the dataset. but I am using dataset.WriteXml method to create the xml file. Is there any option to do this?

Thanks in advance.:) Regards Anuradha

hi all, I am using ORCA to validate the product key in C# 2005 windows application. i am using the following C++ code in a dll to be added to the MSI for validation. UINT __stdcall ValidateSerial(MSIHANDLE hInstall) { TCHAR szPidKey[PIDKEY_LENGTH]; DWORD dwLen = sizeof(szPidKey) / sizeof(szPidKey[0]); ///retrieve the text entered by the user UINT res = MsiGetPropertyA(hInstall, _T("PIDKEY"), szPidKey, &dwLen); if(res != ERROR_SUCCESS) { //fail the installation return 1; } bool snIsValid = true; //validate the text from szPidKey according to your algorithm //put the result in snIsValid //the template we use is <###-####> = ; # digit between 0 and 9 //the algorithm is very simple (XY * Z + 7) * 13 = ABCD / 2 int xy = DIGIT(szPidKey[0]) * 10 + DIGIT(szPidKey[1]); int z = DIGIT(szPidKey[2]); int left = ((xy * z + 7) * 13 ) * 2; int right = DIGIT(szPidKey[4]); right = right * 10 + DIGIT(szPidKey[5]); right = right * 10 + DIGIT(szPidKey[6]); right = right * 10 + DIGIT(szPidKey[7]); snIsValid = (left != 0) && (right != 0) && (left == right); TCHAR * serialValid = NULL; if(snIsValid) serialValid = _T("TRUE"); else { //eventually say something to the user ::MessageBox(0, _T("Invalid Serial Number"), _T("Message"), MB_ICONSTOP); serialValid = _T("FALSE"); } res = MsiSetPropertyA(hInstall, _T("SERIAL_VALIDATION"), serialValid); if(res != ERROR_SUCCESS) { //fail the installation return 1; } //the validation succeeded - even the serial is wrong //if the SERIAL_VALIDATION was set to FALSE the installation will not continue return 0; } but when i execute the above code, i am getting the following error. error LNK2019: unresolved external symbol _MsiSetPropertyA@12 referenced in function "unsigned int __stdcall ValidateSerial(unsigned long)" (?ValidateSerial@@YGIK@Z) CustomAction.obj i have included and I am a beginner in VC++ and could anybody help me with some suggestions Thanks in advance.:) Regards Anuradha

hi all, I want to compare 2 xml files with each other. One xml file is standard on my pc and has the name standard.xml. the other xml file is on the server and has the name server.xml i want to compare these 2 files with each other and if it contains new info it should be added in the pc.xml file. in msdn, i found that XML diff and patch tool is used to compare two xml files. but i do not want to add a additional tool to be installed for this purpose. i tried to do the comparison by getting the nodes in a XmlNodeList and comparing the two nodelists. but i am struck at one point. how can i find out whether a node already exists in a xml document. say for eg, in my xml file,i have a structure like this, <Main> <url type_node="S" tool_tip="http://www.mysite.com/sample.xml">http://www.mysite.com/sample.xml</url> <Category2> <url type_node="S" tool_tip="http://www.mysite.com/sample1.xml">http://www.mysite.com/sample1.xml</url> </Category2> </Main> in this, Category2 is a childnode of Main. i want to check if the url element for sample exists already in the document. how can i do this. i tried using xmldoc.getElementsByTagName(node.innerText); but i am always getting a count of 1 even if the node does not exits in the document. Hope i am clear in my question. Any suggestions?

Thanks in advance.:) Regards Anuradha

hi all, I have a listview in which i am trying to display thumbnail images along with text like the windows explorer. I am able to display the thumbnail view with lots of help from members here. and i tried of sorting out the flickering problem in listview. but when i try to drag the vertical scrollbar down or up rather, the images are not aligned properly and it sort of is overwritten over one another. here is the code i used for drawing the item(having set the owner draw property true).this is just a sample code with the controls having their default names. private void listView1_DrawItem(object sender, System.Windows.Forms.DrawListViewItemEventArgs e) { if (imageList1.Images.Count > 0) { // Draw the item text for views other than the Details view. if (listView1.View != View.Details) { //Image newimage = new Bitmap(imageList1.Images[e.ItemIndex]); Image newimage = new Bitmap(imageList1.Images[0]); left = e.Bounds.Left + 5; top = e.Bounds.Y + this.Height / 7; width = newimage.Width + 5; height = newimage.Height - 25; textbrush = new SolidBrush(Color.FromArgb(255, 236, 233, 216)); Rectangle text_rect = new Rectangle(left, top, width, height); text = e.Item.Text; DrawRoundedRectangle(e.Graphics, new Pen(textbrush), Color.White, text_rect, new Size(8, 8), newimage, text); left = left + 20; top = top + 130; text_rect = new Rectangle(left - 5, top - 25, width - 30, 20); DrawRoundedRectangle(e.Graphics, new Pen(new SolidBrush(Color.White)), Color.White, text_rect, new Size(1, 1), null, text); listView1.EnsureVisible(e.ItemIndex); } } } public void DrawRoundedRectangle(Graphics g, Pen p, Color backColor, Rectangle rc, Size size, Image img, string text) { Point[] points = new Point[8]; //prepare points for poligon points[0].X = rc.Left + size.Width / 2; points[0].Y = rc.Top + 1; points[1].X = rc.Right - size.Width / 2; points[1].Y = rc.Top + 1; points[2].X = rc.Right; points[2].Y = rc.Top + size.Height / 2;
