hresult

I installed Visual Studio 2012 RC recently along with VS 2012 SDK and LightSwitch Extensibility Toolkit. this is the XAML code in my Client.Design -> TControl.XAML file <UserControl x:Class="CustomControls.Presentation.Controls.TControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:framework="clr-namespace:Microsoft.LightSwitch.Presentation.Framework;assembly=Microsoft.LightSwitch.Client"> <Grid Width="Auto"> <Grid.RowDefinitions> <RowDefinition Height="100"></RowDefinition> <RowDefinition Height="40"><

I'm seeing the following exception in my managed (C#) app calling an unmanaged assembly: Caught:System.IO.FileLoadException 'A dynamic link library (DLL) initialization routine failed. (Exception from HRESULT: 0x8007045A)' What does this HRESULT mean, and where should I start in diagnosing this? alternatively the DLL you try to load is trying to load a missing DLL, check with DEPENDS.EXE on the DLL. FileLoadException Class Represents the error that occurs when a Assembly file is found but cannot be loaded. The FileNotFoundException exception is thrown when the file fails to load because it

Here's a code sample creating a COM object: CComPtr<IBaseFilter> pFilter; auto hr = CoCreateInstance(CLSID_DMOWrapperFilter, NULL, CLSCTX_INPROC_SERVER, IID_IBaseFilter, reinterpret_cast<void**>(&pFilter)); I've seen somewhere that checking if CoCreateInstance() succeeded should look like this: if (SUCCEEDED(hr) && pFilter != nullptr) { // code goes here } What if I would check only hr ? Wouldn't it be enough? Should I also check that filter != nullptr ? //would this be enough? if (SUCCEEDED(hr)) { // code goes here } This question also concerns other COM methods like QueryInterface() . Having

I am creating a simple function that creates a random file. To be thread safe, it creates the file in a retry loop and if the file exists it tries again. while (true) { fileName = NewTempFileName(prefix, suffix, directory); if (File.Exists(fileName)) { continue; } try { // Create the file, and close it immediately using (var stream = new FileStream(fileName, FileMode.CreateNew, FileAccess.Write, FileShare.Read)) { break; } } catch (IOException e) { // If the error was because the file exists, try again if ((e.HResult & 0xFFFF) == 0x00000050) { continue; } // else rethrow it throw; } }

Can someone help me decode this HResult? What does it mean? I know the negative stands for a failure. How about the rest of the 10 bits? I referenced MSDN HResult article here , but I am not sure how to determine what my facility and code bits are. More info: _message: "External component has thrown an exception." Data: {System.Collections.ListDictionaryInternal} I'll show you how to do it. Paste the negative number into Calculator (Windows) in programmer mode "Dec" setting. Then convert to "Hex" setting. You get the number: FFFFFFFF80004005. The error is 80004005 which is: 0x80004005 E_FAIL

I've encountered a problem when developing on MS Visual Web Developer 2008 Express Ed. Developing ASP.NET C# on Windows7 64 bit OS. I'm trying to open an Excel document, but it gives me Old format or invalid type library. (Exception from HRESULT: 0x80028018 (TYPE_E_INVDATAREAD)) I did configured the build to all processors (Any CPU, x64, x86) but it doesn't work. I searched the answer on the internet but couldn't find out how to handle it. The weird thing is the same code worked on the same system when I developed on Microsoft Visual C# 2010 Express! how come? isn't it the same dll working

I already have a project that uses alot of COM, and HRESULTS. ANyways i was wondering if its possible to define your own HRESULT, AND be able to use the FormatMessage() for our own HRESULT? I dug around and cant find anything. Any ideas? EDIT Basically i want to define a set of my own HRESULT's instead of just returning E_FAIL. Or one of the other generic ones. Like E_FAIL is fine. But lets say i want to point out that for example the Geoprocessing subsystem crashed or the file is an invalid Raster Image. The application already uses com through out it. Yes of course. Typically you create a
