• Visual C# How to marshal a linked list from C++ to C#

  I have a native C function that returns a linked list in the following form: It actually returns a vlist_s *. /*! The vlist is single linked list that stores void pointers. It has a cursor to traverse the list. */ typedef struct vlist_node_s{ void * item; struct vlist_node_s * next; } vlist_node_t; typedef struct vlist_s{ struct vlist_node_s * head; struct vlist_node_s * tail; struct vlist_node_s * cursor; struct vlist_node_s * cursor_backlink; unsigned int cursor_index; unsigned int count; void *(VLIST_CDECL *malloc) (size_t); void (VLIST_CDECL *free) ( void *); } vlist_t; Is there any way to pass the returned vlist_s pointer back to the C# method that made the original call ...Show All

• Smart Device Development resource assembly error - System_SR_ENU_wm.cab installed.

  I know this has been posted before but can anyone offer any advice on the ' An error message cannot be displayed because an optional resource assembly cannot be found' error other than installing 'System_SR_ENU_wm.cab' All advice I've seen is to install 'System_SR_ENU_wm.cab' but this is definately installed and I'm still getting the error (or rather lack of). I know the exception is a web exception but need to see the details to sort out the problem I have with my mobile application (WM5 on UK english device). The error is raised when the device calls a method on a web service. It works when the device is cradled but when not it starts the GPRS connection as it should but then errors.

• Windows Forms VS 2003, false data concurrency error

• .NET Development Threading fun ;)

  Hello threading professionals, I have something "clean" and interesting for you... please help. I will appreciate it.. I want to solve the problem and (more so) learn about how this thing works.. very interested in the details. In my simple notes-taking simple, once in a blue moon it happens that the GUI stops responding.. I finally took the courage and attached a debugger earlier today when it happened again. With my newly acquired debugging skills I found out where the problem lies and what is happening. However I still don't understand WHY it happens. I imagine that it should be too hard of a challenge for someone with a lot of experience in this subject. Here we go: In my NotesForm, I use a System.Threading.Timer which fires every 20se ...Show All

• Software Development for Windows Vista User Interface to change rules

  Hi, I am just trying to compare Windows workflow rules engine with a typical Business rules engine. In WF, we can make Rulesets and it provides fantastic features like Forward chaining,etc but was wondering if I want to change any rule in the Ruleset I need to change the code and build my application again.

• Windows Forms stop datagridview updating

  Hi Can someone please help I want to stop a datagridview from updating. I've created a strongly typed dataset that contains 1 datatable, when my from loads it initializes the datatable and gives it a couple of rows. I then set the datasource of a datagridview equal to the datatable and then dispose of the datatable. Each row contains a set of variables which I edit from their default values, I then add each row to a list(of dataset.row). These variables are then used to do some calculations, the result of which changes the values in a column, however this slows down the calculation time. If I set the datagridview.datasource=nothing the calculation time shortens, but all the values disappear. Does anyone know of a way to k ...Show All

• Visual Studio Express Editions Filtering

  Hello I'm using VB 2005 pro. I made a little form with a dataviewgrid, textbox and a button. Now when I press the button, the program searches into the bindingsource and filter out what I entered in the textbox. This is the code: (it works PERFECT) Me .ContactBindingSource.Filter = String .Format( "FirstName , Me .TxtSearch.Text) Now when I filter out the database, I have to write the name completely: e.g.: Peter I want to make something that when I enter the first letter: e.g. P, the filter,filters all the names who begins with the letter P.

• .NET Development SOAP FAULT Security

  Hi I have a client who is using my WSE 2.0 web service and is having problems receiving SOAP Faults which my service seems to raise and send OK. One of the issues for my client is that the SOAP fault is not signed. 1) Is it "normal" or "good pracice" to digitally sign SOAP faults 2) If necessary, is there an easy way to do this on WSE 2.0 I ask this because the message itself seems to be constructed by the .Net framework or WSE 2.0.

• .NET Development Porting from saxon

  Hi, First off...I am very new to xslt, and I am really just doing an investigation here to determine which XSLT transfor object we are going to use in a client application we are going to be writing (think client). We already have a web application that uses xslt to transform xml files that contain data gathered in a lab. That web app uses saxon, perhaps partially due to the fact that saxon implementents XSLT 2.0. Regardless, since I am going to be interested in displaying the same data (in an environment where we don't necessarily have access to this web application) using the xml files and xslt templates, it would be nice If I could get away with modifying these as little as possible. I have already found out that the element xsl:f ...Show All
