LoadLibrary on OCX file fails in Windows 7 x64

由 末鹿安然 提交于 2019-12-02 07:52:47
I need to open a html help file from within a legacy windows application written in old version of C++ Builder. HtmlHelp is loaded via HtmlHelp.ocx, which I am loading via LoadLibrary. This has worked fine for years, but it does not work anymore in Windows 7 x64. It might also fail under Windows7 x86, but I don't have any computer with this OS, so I can't try it out at the moment. I am loading hhctrl.ocx dynamically as follows: #define HHPathRegKey "CLSID\\{adb880a6-d8ff-11cf-9377-00aa003b7a11}\\InprocServer32" bool THTMLHelper::LoadHtmlHelp() { HKEY HHKey; DWORD PathSize = 255; char Path[255]

MVC Method to output unordered list from the ListBoxFor method

由 隐身守侯 提交于 2019-12-02 06:52:25
问题 In MVC3, I want to change the HTML output by the Html.ListBoxFor method so that instead of an HTML list box with all the available values (and the selected values highlighted), I want to simply output an unordered list (UL, LI) of the selected items and not a SELECT element. The issue is that I want to keep exactly the same method signature as the ListBoxFor method , accepting a MultiSelectList object and a List which is the selected values. I then want the unordered list to only output the

Are HTML helpers worth using with complex markup?

由 喜你入骨 提交于 2019-12-02 04:25:26
问题 Should I persist with using HTML helpers, or just use plain HTML? I've been using HTML helpers for a while now and really enjoyed using them. Recently I've started using CSS frameworks such as Twitter Bootstrap and I'm finding that my markup is too complex to use the standard HTML helpers. Of course, I still use Url.Action() for generating links and sometimes @Html.TextBoxFor() or similar for simple forms, but, for example, I'm finding some helpers like Html.ActionLink() or Using Html

MVC3 HTMLHelper defaults

由 隐身守侯 提交于 2019-12-02 04:15:28
问题 I have an html helper that I'd like to set a default on. @Html.EditorFor(model => model.DateFrom) What's the syntax to set the default value of the helper if the model.DateFrom is null? 回答1: I dont think that using EditorFor you can set a default value. Consider setting it in the accessors on your model? To do it on other types ( TextBoxFor etc ) You can set a value but not a default value. So you would need to do: @if(Model.something == null) { @Html.TextBoxFor(m => m.ID, new { @Value =

Controlling Output Indentation in ASP.Net MVC

由 无人久伴 提交于 2019-12-02 02:52:39
问题 My colleague is extremely 'hot' on properly formatted and indented html being delivered to the client browser. This is so that the page source is easily readable by a human. Firstly, if I have a partial view that is used in a number of different areas in my site, should the rendering engine be automatically formatting the indentations for me (ala setting the Formatting property on an XmlTextWriter)? Secondly, my colleague has created a number of HtmlHelper extension methods for writing to the
