winform ui

Multithreading is an old topic. Today I will talk about the most basic threads, UI threads and background threads. An exception occurs when you directly operate the UI control in the background thread (the Inter-thread operation is invalid: access it from a thread that does not create the control "XX ). How can this problem be solved? The key points are in the proxy and invokerequired attributes, and the

Review and description We have summarized or demonstrated the "commodity Dictionary", "commodity warehouse receiving", and "commodity inventory query" modules in detail, these modules involve simple data addition, deletion, and repair, as well as complex business processing transactions and business layer extraction, common query and report printing technologies and basic dictionary cache query technologies in MIS systems. Content Today, we will use another technology to implement another

Most We have been working on winform-related systems for the past year. We have some ideas for winform's uidesign (mainly busy, so many of them are just ideas and there are no development instances yet) As for winui, the ideal situation should be cool appearance, which gives users a good user experience and impression, while taking into account both powerful functions and easy development. However, based on the traditional. Net windowsforms, except f

Common Phenomenon: You can see the cell cursor on the DataGrid and run ar

Preface: Why use IE to open WinForm personal feel, WinForm deployment client too trouble such as Kingdee · UF, Winfrom patching too much trouble, adding new features to deploy a lot of time, so why not use IE to open it? This does not require the deployment of the client, and the file update only needs to be done at server. If you have an idea, you must realize it.Advantages.

Why do I need to use ie to open winform? I personally think it is too troublesome to deploy the client using winform, such as Kingdee UFIDA and winfrom. It takes a lot of time to add new features and then deploy them; why can't I open it with IE? In this way, you do not need to deploy the client. File Updates only need to be performed on the server. If you have an idea, you must implement it ..Advantages:

modules are a combination of multiple common modules. They may be the following common modules: general permission module, general dictionary module, general attachment management module, and general personnel management module. 3. Implementation of a hybrid framework To better understand the Winform development framework, I will introduce the implementation of this hybrid framework through the general dictionary module, one of the auxiliary modules.

It's okay at noon. I took a few pictures I drew when I graduated last year and introduced the process of running the Winform application and the application of TCP protocol in Winform. If you have basic information such as the Windows message mechanism, you can understand these two images. (1) program running structure of the Winform Application (2) Applicati

Asynchronously load data in WinForm and use the progress bar. winform progress bar In the WinForm program, the UI may be suspended due to loading a large amount of data, which is unfriendly to users.

The Winform application implements the universal Mask Layer 2 and the winform mask. Previously, we have published Winform application universal mask layer and Winform application universal message window. These two mask layers are based on the pop-up window, today we will share with you a simple but user-friendly imple
