• Windows Forms Control to display images

  I am helping to develop an application which is essentially a chat area. For the most part, everything works well however I seem to be running into some limitations in the controls available. Or maybe more likely I am just not used to everything I can use... so many changes in the dot net side. Anyway :) If I use a VB form with a WebBrowser control for the interface to display received messages, I can easily scan the incoming text for various key words (i.e. :roflmao:) and then change them to a location where various images (jpg, gif, whatever) are located and display the image rather than the text. Reformat the layout to html specs and display that in the control. This works well, except that the WebBrowser control does not seem to sup ...Show All

Please help. Thanks Then go straight ahead by creating a job, defining a schedule and inserting one step f ...Show All

• Smart Device Development System.Thread.Timer help

  Hi, I was hoping some could help with a threading issue that uses a timer. I would like to have a piece of code execute every 10, 15 or 30 minutes. (users choice). So, as users are using the application every ten minutes I need to do write something to the database. Sorry I am so unfamiliar with the System.Thread.Timer object I do not even no wherre to begin. Any help would be greatly appreciated. A logical first step would be to get familiar with it, e.g. by reading MSDN article.

• .NET Development TimeStamp Dataset DAAB

  Hi, What dbtype would I use for the addinparameter method of DAAB , when mapping to a timestamp column of a dataset I have tried DbType.Byte , but this will not compile Do I need to cast the value returned by the dataset Do I need to perform a cast at the database before returning the timestamp column , Please help! u You can use int64. For example Int64 rowVersion; rowVersion = Convert .ToInt64(p11.Value); here p11 is the parameter mapped to the parameter of stored procedure which returns the Timestamp. I didn't do any CAST on the stored procedure side. If you are doing the CAST on stored procedure then the returned parameter can directly stored in DbType.Int64 variable. Hope this resol ...Show All

• Windows Search Technologies Problem crawling with a hierarchical custom protocol handler

  I have developed a hierarchical custom protocol handler that I'm integrating with Windows Search on Vista. The handler has a IUrlAccessor and IFilter implementation that enumerates the contents of a directory by returning the search URL of each "file" in the directory as a text chunk with the STAT_CHUNK structure specifying the GathererPropset and PID_GTHR_DIRLINK propid. My understanding is that the indexer should take these URLs and queue them for indexing, in which case I should see subsequent calls to CreateAccessor with those URLs. However, instead I'm seeing the indexer call CreateAccessor once to get the directory accessor, then it reads the dirlink text chunks, but it never make the expected additional calls to Create ...Show All

• Visual C++ Timer stops after a while

  I have an MFC application using 5 system timers with the following time-out values: 10 minutes 1 second 0.5 second 0.1 second 0.01 second It seems that all timers stop generating WM_TIMER after the program runs for a few days and everything else of the program works fine. Has anyone ever seen this kind of problem Am I using too many timers draining too much system resorce I have just combined the 0.5 second timer with 0.1 second timer into one to see if this helps. Since this is not a C++ language or compiler question I would suggest you ask this question in one of the MSDN discussion groups. Kernels is probably the best match. http://msdn.microsoft.com/newsgroups/default.aspx dg=microsoft.publi ...Show All

  How do you place five choices from a combo box into a loop. In other words I have five items in a combo box that I want to place in a "for loop". For example, I have items such as choice1, choice2, choice3, choice4 and choice5 inserted into a combo box. Also I would like to know if it is possible to place these choices into a "do while loop". Any help welcome The controls has an items property which is simply a collection.   You can iterate around it using for each construct or determine how many items there are and then use any of the looping constructs. There is nothing special about the items collection in a combobox as against any other collection and iterating through the items. Is there an ...Show All

I am a little confused about the field "Assinned To" and have a question about it. What I wonder is what is filling the field I thought it was all the users in the domain and that this was due to that the server belongs to this domain, but the list does not contain all users.
