directx11 – FormatMessage does not work for HRESULT returned by Direct3D 11

I use Windows 7 x64 and Visual Studio 17 (v15.9.7).

Say I'm trying to create a channel using IDXGIFactory2 :: CreateSwapChainForHwnd and go into DXGI_SCALING_NONE. I will receive the following message in the debug output (if I have enabled Direct3D debugging):

DXGI ERROR: IDXGIFactory :: CreateSwapChain: DXGI_SCALING_NONE is only supported on Win8 and later. DXGI_SWAP_CHAIN_DESC {SwapChainType = ..._ HWND, BufferDesc = DXGI_MODE_DESC1 {Width = 8} _UNSPECIFIED, Stereo = FALSE}, SampleDesc = DXGI_SAMPLE_DESC {Count = 1, Quality = 0}, BufferUsage = 0x20, BufferCount = 2, OutputWindow = 0x0000000000290738, Scaling = ..._ NONE, Windowed = TRUE, TRUE, TRUE, SwapEffect = ... AlphaMode = ..._ NOT SPECIFIED, flags = 0x0} [ MISCELLANEOUS ERROR #175: ]

The function returns 0x887a0001 in the form of HRESULT. If I put @ err, hr in the monitoring window, I get a nice error message:

ERROR_MOD_NOT_FOUND: The specified module was not found.

However, if I spend this HRESULT at FormatMessage, it just puts NO in the output and returns 0. @ err, hr informs me that the new error is ERROR_MR_MID_NOT_FOUND: The system can not find the text of the message with the message number 0x% 1 in the message file for% 2.

My questions are:

  1. Why is it FormatMessage do not give me the correct error string (the one starting with ERROR_MOD_NOT_FOUND ...)?
  2. Where does Visual Studio get these nice error strings?
  3. Can I get them too? Who am I paying?

PS. I'm using the Windows 10 SDK version of DX11, not the old version of DirectX SDK. So, I can not really create a link to dxerr.lib no more.

This is the code used to print the error message:

LPTSTR error_text = NULL;
(LPTSTR) & error_text, 0,

A ♪♪♪♪♪ vs IOS

We have seen the factors that would help choose the platform to use for your first mobile applications, the sad truth remains: there is no yes or no answer to the platform with which startups have to go among the market share of Aan vs ios us.

However, although we have trouble finding you an answer to 'An ♪♪♪♪♪ vs iOS: which platform should be chosen by the startups', we give you the answer to the question "When."

When should startups choose iOS first

If you want to integrate the target demographics of the app store, you need to put the first mobile application of your startup on iOS, spending your expenses in an iPhone application development company. Plus, if you're not influenced by the ability of an app to like and be moved to the home screen, the less fragmented world of Apple can s & # 39; Prove useful because you will not have to waste time creating your app for multiple devices.

The advantages of concentration and the ability to generate high revenues make the development of iPhone applications advantageous for business.

When should startups choose An- ♪♪♪♪♪ First

You should start with An- ♪♪♪♪♪ if your audience is not focused on a specific place. Plus, if there are lots of customization basics in your mobile app, use An ♪♪♪♪♪. The benefits of the scope and customization provided by the platform make it almost indispensable for companies to have an An ♪♪♪♪♪ application.

When do startups need to choose both An An and iOS
Vs iOS: what platform that start-ups should choose for the first mobile application also have a third option, one that ends the confusion between iPhone or An – Launch the application on An ♪♪♪♪♪ and on iOS.

If the selection is to be chosen as a solution by companies with sufficient time and money, you need to invest in mobile application development companies that specialize in the development of multiplatform applications in order to seize the opportunity to enjoy the best of all.

Now that we have seen everything – The factors that affect the choice of iOS vs iOS for startups and situations in which we consider that one is better than the other – now is the time to answer a very futuristic and logical question – When does a company have to go from one platform to another?

When does your startup need to extend from one platform to another?

The answer to this question lies in the fact that your application uses all the advantages of the current platform. If your app has reached a point where it now generates constant revenue from the App Store, expand it to Play Store for greater reach.

If your An ♪♪♪♪♪ app has gained enough followers on the Play Store, increase the extent of monetization by directing it to the App Store.


getchanges – Tracking changes to items with Nintex Workflow – Result not returned

I use the following solution to track changes to items:

Brief description – Whenever an item is updated, the workflow compares the current values ​​to the previously defined InitialChangeToken by running the "GetListItemChangesSinceToken" web request.

Although everything works fine in most cases, the following problem sometimes appears: If the item's InitialChangeToken was set a few months ago, no results are returned when updating the item. # 39; element. If new InitialChangeToken is set again, the changed fields are returned successfully.

What could cause that? I compared the previous and new xmls for InitialChangeToken and there were some differences – one field had the new parameter Version = "2", the version was also modified for two workflows and we changed the threshold of List view since the first InitialChangeToken.
Are there situations in which we need to regenerate InitialChangeToken for all items – when list settings are changed, forms / workflows are updated, etc.?

pnp powershell – Get-PNPWorkflowInstance object returned

New in Powershell, keep that in mind …. I have successfully used Powershell scripts to work on my Sharepoint site. What I am not sure about, is this. Given certain functions, I am almost certain that an object is returned from my pnp function but what I am not sure (and that is the general part of my question) if an object is returned, what is the object and how can i access its properties … realizing that this is probably different for each object returned.

For example, I published Get-PNPWorkflowInstance to find suspended workflows and delete them. The code loops, finds, and kills the suspended job streams. Here is part of this code.

The question is this. What is the object and how to access the object or expose its properties. I've tried to find documentation on this, but I think it's my lack of knowledge (a void I want to fill) in terms of OOP. Thank you.

Foreach ($ Item in $ Items)
Get-PnPWorkflowInstance -List $ List -ListItem $ Item | Where-Object {($.Status -eq "Suspended" -or $.Status -eq "Not started" -or $.Status -eq "Started" -or $.Status -eq "Startup failed" -or $.Status -eq "Error Occurred" -or $.Status -eq "Canceled" -or $.Status -eq "Canceled" -or $.Status -eq "Start failed (retry)" -or- $.Status -eq "An error has occurred (retry)")} |
Foreach-Object {
$ WorkflowInstance = $

$ Subscription = $ AllSubs | Where-object {$.Id -eq $ WorkflowInstance.WorkflowSubscriptionId}
Stop-PnPWorkflowInstance -Identity $ _ -Verbose -Force
Start-PnPWorkflowInstance -Subscription $ Subscription -ListItem $ Item.Id
