Visual C++ General approach to native dll using managed wrappers
I have a native dll that exports some structures and functions. The functions use pointers to the native structures to populate the data. I would like to wrap the structures and expose some of the members for data binding. What is the right approach to this problem. I am using VS 2005. For example: //------------------------------------------Native dll typedef struct{ int var; AnotherNativeStruct* pType; }NativeStruct __declspec(dllexport) BOOL NativeFunction( NativeStruct* data ) ; //<- Modifies var and pType upon return // -------------------------------------------Managed using namespace System; public ref class Wrapper { public: // Some constructor, perhaps Wrapper( NativeFunction ...Show All

Windows Live Developer Forums Layers on and off
I am develpoing a map that contains many pushpins in a small area. I would like to turn them on and off by using checkboxes. Doe anyone know how to go about this I really appriciate everyone's help and time. "Jared H" I understand what you are saying about trying to call more than one layer with the same UniqueID being a problem. I want to first get it working with one layer as a proof of concept and one it gets up and running I will prob. go with your solution. I added map.onLoadMap = AddMyLayer1(); to the GetMap function but am finding it does not load the layer and thus i can still not turn the layer on and off.

Visual Studio Upgrading Headaches
I am a fan of GAT, but today, I finally upgraded to June CTP and am extremely frustrated with the upgrade story. I tried to just install the June CTP, and it tells me I need to uninstall the previous versions first (can we work on an in-place upgrade ). Anyway, I unistall... excuse me... *try* to uninstall the previous versions, but in order to do that I have to uninstall *every* guidance package that was built on top of GAX. I have built 5 or 6 of them, so this is going to be painful... especially since I uninstalled GAT first and overwrote my installer with the june CTP. So, now I can't uninstall the packages built on top of GAX until I reinstall GAT (some of the packages were just registered through the IDE and the installer was n ...Show All

SQL Server Custom Data Flow Task throwing error when run from command prompt
Hi, I developed a custom data flow task in .net 2.0 using Visual Studio 2005. I installed it into GAC using GACUTIL and also copied it into the pipeline directory. This task runs absolutely fine when I run it on my local machine both in BIDS and using the script in windows 2000 environment. However, when I deployed this package into a windows 2003 server, the package fails at the custom task level. I checked the GAC in windows\assembly directory and it is present. Also I copied the file into the PipeLine directory and verified that I copied it into the correct pipeline directory by checking the registry. The version of the assembly is still Debug. I looked up documentation in MSDN but there is very little information about the error ...Show All
Windows Forms Finding edited rows in DataGridView
Hi, In my windows application I am using DataGridView as my grid control. I populated let's say 10 rows of data and modified 3 random rows. How can I trap those 3 modified rows without going through the whole row set The DataSource of my grid is a DataView which I create it programmatically. I tried this event: void GridView_CellValueChanged( object sender, DataGridViewCellEventArgs e) { int col = e.ColumnIndex; DataGridViewCell cell = _form.GridView[col, e.RowIndex]; DataGridViewRow row = cell.OwningRow; DataRowView originalRow = ( DataRowView )row.DataBoundItem; // if the fifth column was edited if (col == 4) { if (originalRow.Row.ItemArray[0] != cell.Value) { // save the change ...Show All
SQL Server Date out of range?!
Greetings! I have a data source that gets generated based on a variable with the following SQL : "select * from result where deletion_ind = 1 and when_deleted >= '" + (dt_str, 50, 1252) @[User::Last_Run_Date] + "'" But when I run my package I get an error message saying: The conversion of CHAR to DATETIME resulted in a DATETIME value out of range The Last_Run_Date variable is set to '2006-06-25 14:35:05.450' When I run the code in a QA session it works, but in the package it complains!

Software Development for Windows Vista Long running workflow exposed as web service
Hello all: I am trying to write a workflow for a requests system. We want this WF exposed as a webservice. A user would go to a CreateRequest.aspx page, fill out the form and hit submit. Submit calls a CreateRequest function on the webservice. The WF then populates a business object, validates it (ensure date needed > today and a Title is given) then saves the business object into our database. At that point we need to workflow to just sit around and wait for something to happen to the request (assign it, change its status to "In_Progress", "Testing" etc). There are various steps for this process (DirectorApproval, Work_In_Progress, Testing, Read_For_Installation, etc). So, how do we do this with web services A ...Show All

Windows Forms ContainerControl inside another ContainerControl
<.NETFramework> I am facing problems using a ContainerControl inside another ContainerControl. The child ContainerControl is not getting on the design surface probably. I'm not being able to drop any control (e.g a Button) on the inner ContainerControl. It is dropping the control (Button) on the outer ContainerControl instead. I know there is something like EnableDesignMode in Framewrok 2.0. But I cannot find it in Framewrok 1.1. I would also like to share that I'm working on a TableControl that will be just like an HTML Table Control. I also know that Microsoft has provided a TableLayoutPanel with Framework 2.0. But due to some requirements I cannot go for it. Currently I'm trying to design something like this: <Table type= ...Show All
Visual Studio Page breaks before table
I have a local report with a one to many relation, using a list to the "one" fields and a subreport (table) to get the "many"/details. It's like a order/order details relation. When the data doesn't fit in a single page, the table/subreport containing the detais breaks all to the next page. What I want was in that case is that only the rows on the detais that don't fit in the page should break into the next page, and not the hole table. I solve this matter putting a page break at the end of the table, but in this case I can’t put anything more after the subreport/table. Does any one know how to solve this ...Show All
