• Gadgets Shared memory reading by gadget

  Hi All, Is it possible to access to shared memory by gadget Do you know any implementation/sample gadget/projects that uses shared memory (storing some data by process for example, and reading and displaying this info by the gadget). Thanks No, but there are two workaround: 1. Write to a file in the Gadget directory and monitor it 2. Write to the registry Personally, I'd go with option 2 as it's neater. eg var oShell = new ActiveXObject("WScript.Shell"); oShell.RegRead("HKCU\\Software\\My Company\\My Gadget Name\\My Value Name"); oShell.RegWrite( HKCU\\Software\\My Company\\My Gadget Name\\My Value Name\\","My Value" , "REG_SZ"); ...Show All

• Microsoft ISV Community Center Forums Delete Unwanted rows based on value in cell

  Hi all, I have to loop through a range of rows with an excel sheet and delete unwanted data. To identify the rows to be deleted I have to do the following: Firstly I must start at A1 and check if it contains the value "Product", if not i go to the next row but if it does i must then delete this row and go to the next. I must then check that the next cell contains the value "Total", if not i go to the next row but if it does i must then delete this row and go to the next. I then need to delete each of the next rows until i find the next cell that contains the value "Product", delete this cell and then go through each of the next rows until i find the next cell that contains the value "Total&quo ...Show All

• Software Development for Windows Vista External Events, ThreadPool and WaitForIdle

  Hi, Given: stateMachineWorkfow, which waits for some external events that are being sent to it via ExternalDataExchangeService. The service code contains something like: public event EventHandler<ServiceEventArgs> FireEvent; void TestFireEvent { ThreadPool.QueueUserWorkItem(delegate { if (FireEvent != null) { FireEvent(this, args); } }); } where ServiceEventArgs have 'WaitForIdle' property set to 'true'. Such a code makes the workflow runtime to wait till the workflow becomes idle, before delivering the event. Therefore the thread in the thread pool may be waiting for quite a long time, because we can not be sure if the workflow will become idle fast enough. This leads to potential problems because t ...Show All

• Windows Forms Creating”alert” when new file arrives

  Hello! I hope this is the proper forum for this. Every day a computer sends out new files to a certain folder in my computer. I am to check these files when they arrive, ASAP. However they come within a one hour window. This means that I have to check my folder every five minutes during the waiting time if I want to be able to check the files as they arrive. Therefore I would like to make some form of “alert” that notifies me when new files arrive in my folder, preferably but necessarily using audio. Is this possible If so how can you do it Any help very much appreciated! Thanks a lot in advance! I know I can minimize the window showing the folder and just have it at the corner of my screen but that is not very convenient as I ...Show All

• SQL Server Connection manager validation within UI

  Hi all, I need to validate a custom connection manager within its custom user interface, like the FlatFileConnectionManager does it, by showing errors and warnings at the bottom of the window. How can I do that since SSIS provides only a ConnectionManager object with the IDtsConnectionManagerUI::Initialize method, and this object doesn't contain any Validate method Note that for a custom data flow component, SSIS provides a ComponentMetaData object which supports a Validate method. Thanks. Pascal I can't call the Validate method of my custom connection manager because SSIS doesn't give me my object but a ConnectionManager which is not a ConnectionManagerBase type... ...Show All

  i want to know how keyboard/mouse interact with the system how any instruction is get executed by the system whenever any key is pressed in mouse/keyboard e.g. when we pressed 'a' key in the keyboard then exactly what happens in the system how system execute that instruction i think my question is clear to you , please give ans of my query n if any doubt in question then ask your welcome. thank you Bhupi, This is a really good question.

• Smart Device Development Memory Efficiant Coding Practices for Mobile Devices (Should I be more careful?)

  Hi All, I'm writing my first Windows Mobile 5 application using C# and .NETCF2.0. I've had my ups and downs but all is going very well at present. I've recently written a couple of File IO routines that 1) Reads INI style files 2) Reads CSV style files. I'm very concerned about the way I'm reading these files. My issue is with available system memory. The target device for this application is a HP IPaq hw6915. The device is telling me there is a mere 23Mb of available system memory. Ok, no surprises there really, there are smart devices with less. With this in mind if I read a whole 24Mb file into memory I'll saturate the device. Now I'm not worried about the INI file reader as this reads the whole file in (Not that big in theor ...Show All
