Re: How to retrieve image with Html led mike6-Jul-06 6:26 led mike 6-Jul-06 6:26  I am not trying to be rude but HTTP is a fairly large protocol and using a forum is not the way to learn it. Go and study the HTTP protocol so that you "know" what you need to develop before you start writing code. try Google: HTTP protocol tutorial good luck "Just about every question you've asked over the last 3-4 days has been "urgent". Perhaps a little planning would be helpful?"

Roopesh Singh Gangwar Re: tiff file reading rubben6-Jul-06 5:17 rubben 6-Jul-06 5:17  Have you tried FreeImage? It comes with a nice C# wrapper and seems to handle every TIFF type I've tried except JPEG 6.0 compression. If you need low-level stuff, you could write a wrapper for libtiff. Re: tiff file reading roopeshgangwar6-Jul-06 9:19 roopeshgangwar 6-Jul-06 9:19  No i have not tried FreeImage. If you have code for that can u share it with me.

If I know the Tag (full path of the node), how can I use it in order of Checking the node. Thanks -- modified at 9:49 Thursday 6th July, 2006 Re: Treeview Nader Elshehabi6-Jul-06 5:18 Nader Elshehabi 6-Jul-06 5:18  Hello Try to parse your tag & select them node by node, until you reach your target node. Slow, but sure Don't forget to put in mind that the tag may be in incorrect format eg. -NOT A REAL CODE- try { string MyTag = TheTag Get firstNode Name Select it from the root remove its name from MyTag while(MyTag.Length > 0) { Get NextNode Name Select NextNode from the SelectedNode.Nodes Remove its name from MyTag } } catch { //error } //Now We got our node Regards array exporting in c++ dll to c# client Tugberk_Kara6-Jul-06 3:21 Tugberk_Kara 6-Jul-06 3:21  I have a function in c++ returning array as: int * funcArg(int *a ) { int * DLLArg; DLLArg=a; return DLLArg; }; I exported this function in dll( I checked with dumpbin.exe) I declared this function in c# client as: [DllImport("DenemeNonMfcDll.dll")] public extern static int [] funcArg(int [] a); And I called this function in c# client as: int [] intArray; intArray = new int[3] {0, 1, 2}; foreach (int num in funcArg(intArray)) { System.Console.WriteLine(num.ToString()); } But I got System.Runtime.InteropServices.MarshalDirectiveException and it says it can not marshal return value.

I have a user-control with tons of controls in it such as text-boxes, combo-boxes, etc. I want to display a BIG RED LABEL titled "VOID" over this user-control sometimes when the control is displayed. But I want the user to still be able to read the data in the controls behind the label. When I set the back-color property of the label to transparent, it doesn't seem to work. I have also tried creating a custom label and over-riding the CreateParams property. I have also now tried making a graphics and using the drawstring method. However, I once again cannot figure out a way to make the graphic the top most control over the other controls. I even changed the other controls z-order. PLEASE HELP AS I AM BECOMING DESPERATE!! Re: Displaying a label over other controls Not Active6-Jul-06 3:30 Not Active 6-Jul-06 3:30  I believe the only way you're are going to accomplish this would be to override the control's OnPaint method and draw your text. Re: Displaying a label over other controls anderde6-Jul-06 3:44 anderde 6-Jul-06 3:44  By drawing it in the OnPaint method, I still have not figured out how to make the Graphics object the top most control. Re: Displaying a label over other controls Not Active6-Jul-06 3:59 Not Active 6-Jul-06 3:59  You can't make the graphics object the top most control because it isn't a control. The graphics object is the representation of the control, or image, or print page, etc. The control is painted on the screen using the graphics object so in your case you would do something like public void OnPaint(...) { base.OnPaint() Graphics.DrawString(...) } Caution: Not actual working code. Re: Displaying a label over other controls anderde6-Jul-06 4:31 anderde 6-Jul-06 4:31  Thank you so much for your help. Your explanation is helping me to better understand the problem. I now believe that it must be an ordering problem. I have tried drawing the strings in the OnPaint method but the strings still appear behind the controls. I believe that the controls are being drawn after the onPaint method is called. I tried overriding the onPaint method exactly as you suggested (calling base.OnPaint() first and then Graphics.DrawString()) - however, the string is still painted behind the controls. How can I ensure that my Graphic is drawn last on the control?

Please visit the following link: http://www.codeproject.com/cs/miscctrl/SimpleLine.asp Enterprise Library January 2006 Brendan Vogt6-Jul-06 2:41 Brendan Vogt 6-Jul-06 2:41  Hi, I installed the Enterprise Library January 2006 on my PC and it compiled and built the project. Now when I rebuild the solution, it still says to me that the date on the dll or of 2 days ago (the date when I installed Enterprise Library). I'm referring to adding a reference to the Data Application Block dll. Why is it that when I add it to my bin folder in my Web Project using Add Reference, then it goes and adds about 6 files, namely: Microsoft.Practices.EnterpriseLibrary.Common.dll Microsoft.Practices.EnterpriseLibrary.Common.xml Microsoft.Practices.EnterpriseLibrary.Data.dll Microsoft.Practices.EnterpriseLibrary.Data.xml Microsoft.Practices.ObjectBuilder.dll Microsoft.Practices.ObjectBuilder.xml I read at that I must add the following 2 DLL files: Microsoft.Practices.EnterpriseLibrary.Common.dll and, Microsoft.Practices.EnterpriseLibrary.Data.dll When I check at the SDK of the PayPal Starter Kit, then the DAAB dll that they reference is called something like Microsoft.ApplicationBlocks.Data.dll. Why is this? Please can someone explain. Regards, ma se Re: Enterprise Library January 2006 Not Active6-Jul-06 2:54 Not Active 6-Jul-06 2:54  ...Common.dll is, well, for common pieces of the EntLib ...Data.dll is of course for the data access block (previously called Data Access Application Block, PayPal must be using an older version) ..ObjectBuilder.dll is used to create the objects necessary for the Data block The xml files are the compiled documentation files and should not be included in your application Re: Enterprise Library January 2006 Brendan Vogt6-Jul-06 3:03 Brendan Vogt 6-Jul-06 3:03  "previously called Data Access Application Block", what do you mean by this and what is it used for now? So if I remove the xml files nothing will crash? Are all 3 dll files required? Have you got extensive knowledge about the new application blocks? Just curious. Re: Enterprise Library January 2006 Not Active6-Jul-06 3:15 Not Active 6-Jul-06 3:15  Enterprise Library features new and updated versions of application blocks that were previously available as stand-alone application blocks. http://www.gotdotnet.com/codegallery/codegallery.aspx?id=295a464a-6072-4e25-94e2-91be63527327[^] ma se wrote: Are all 3 dll files required? Only if you want the app to work I wouldn't say extensive knowledge but I have been using the EntLib for some time. Re: Enterprise Library January 2006 Brendan Vogt6-Jul-06 3:44 Brendan Vogt 6-Jul-06 3:44  I just want to ask something. I usually had my classes broken up into BLL classes and my DAL classes. Would I still make use of the DAL classes?? I'm assuming so because you would have different method calls, like GetOrders(), or GetCustomers(), and each method would do it own thing with the results returned. Re: Enterprise Library January 2006 Not Active6-Jul-06 4:05 Not Active 6-Jul-06 4:05  Obsolutely. Your design doesn't change, you just use the EntLib in the DAL. Re: Enterprise Library January 2006 Brendan Vogt6-Jul-06 4:42 Brendan Vogt 6-Jul-06 4:42  Hi Mark, I just want to thank you in guiding me. I appreciate it. Once I know a bit more about the DAAB, then I want to start with the the other application blocks, lets say caching, exception and logging. Take care!!

Its having a MDI form and many child forms. What i have to do is when i click a menu from the MDI window i get a form having a datagrid and many other calculations done and at the end of the page i have a print button. I want to print that entire page when i click the print button. I got a code from google but what it does is capture the screen and then prints. since it captures only what we can see in the screen i dont get the rest of the content which is visible only if i scroll down the window. i want the entire page to be printed.
