Prerequisities in Visual Studio Projects In Configuration at the top of the dialog, did you try to select either Release or Debug? That should enable the Prerequisites… button. Unecessary, outdated prerequisites? One pet-peeve of mine: is it really necessary to include the .NET runtime as a prerequisite when most users have it installed by their … Read more
Add a SaveFileDialog control to your form, then add the following code on your WebBrowser’s Navigating event: private void webBrowser1_Navigating(object sender, WebBrowserNavigatingEventArgs e) { if (e.Url.Segments[e.Url.Segments.Length – 1].EndsWith(“.pdf”)) { e.Cancel = true; string filepath = null; saveFileDialog1.FileName = e.Url.Segments[e.Url.Segments.Length – 1]; if (saveFileDialog1.ShowDialog() == DialogResult.OK) { filepath = saveFileDialog1.FileName; WebClient client = new WebClient(); client.DownloadFileCompleted … Read more
Well, since this is a datagridview… Sorry for the ‘winforms’ in the question… but I could just do this.. scrolling up or down one row. Scroll up: this.FirstDisplayedScrollingRowIndex = this.FirstDisplayedScrollingRowIndex – 1 Scroll Down: this.FirstDisplayedScrollingRowIndex = this.FirstDisplayedScrollingRowIndex + 1; You’ve gotta make sure to check that the numbers don’t go out of bounds though.
I think this is a brilliant question – and I think there is need of a better answer. Surely the only reason is that there is something in a framework somewhere that isn’t very thread-safe. That “something” is almost every single instance member on every single control in System.Windows.Forms. The MSDN documentation for many controls … Read more
Take into account that this is a hack. I managed to solve that problem and the lack of API functionality doing a trivial and nasty thing. I’ll show you this with code: dim source as AutoCompleteStringCollection = new AutoCompleteStringColection() dim values() as String = new String() {” Monday”, _ ” Tuesday”, _ ” Wednesday”, _ … Read more
The sanctified method is to use CryptoAPI and the Data Protection APIs. To encrypt, use something like this (C++): DATA_BLOB blobIn, blobOut; blobIn.pbData=(BYTE*)data; blobIn.cbData=wcslen(data)*sizeof(WCHAR); CryptProtectData(&blobIn, description, NULL, NULL, NULL, CRYPTPROTECT_LOCAL_MACHINE | CRYPTPROTECT_UI_FORBIDDEN, &blobOut); _encrypted=blobOut.pbData; _length=blobOut.cbData; Decryption is the opposite: DATA_BLOB blobIn, blobOut; blobIn.pbData=const_cast<BYTE*>(data); blobIn.cbData=length; CryptUnprotectData(&blobIn, NULL, NULL, NULL, NULL, CRYPTPROTECT_UI_FORBIDDEN, &blobOut); std::wstring _decrypted; _decrypted.assign((LPCWSTR)blobOut.pbData,(LPCWSTR)blobOut.pbData+blobOut.cbData/sizeof(WCHAR)); If … Read more
I think that there are two answers here… really just one answer to “Should I” and one answer to “Could I”. As far as “Could I”, it is certainly possible. MVVM really just relies on a view that can bind to a view model. Since WinForms supports binding, this certainly is possible. You may need … Read more
No the standard button does not react to double clicks. See the documentation for the Button.DoubleClick event. It doesn’t react to double clicks because in Windows buttons always react to clicks and never to double clicks. Do you hate your users? Because you’ll be creating a button that acts differently than any other button in … Read more
Here is a code of a class ListViewExtender that you can reuse. It’s not a derived class of ListView, basically you just declare that a specific column is displayed as buttons instead of text. The button’s text is the subItem’s text. It allows big sized list views without problems, does not use p/invoke, and also … Read more
Yes – it was included as part of the Visual Studio 2008 Service Pack 1 – at least for C++/MFC support anyhow. See this similar question for more info.
