Asp.net - Signing Active X Control And Marking As Safe?
Dec 9, 2010
I have developed an active x control and signed it with certificate. I know that digital signing is needed , so that the browser knows that the active x comes valid source.My asp.net form has a button , which invokes a method on activex control as -[code]....
But it errors on browser stating that the - IE has blocked this site from using an active x control in an unsafe manner. ( Please see attachment).So should I have to develop the active x control which implement IObjectSafety and also signed digitally, so that it can execute on client browser without any warnings from IE. Any examples.
Where can I get a free code signing certificate for signing my applications? Ascertia used to give them out for free but apparently they don't anymore.
I want to get the active control (control which has the focus or where the cursor is on) each time the cursor moves to another control or each time a control receives a focus.
If you are interested, I am doing this because I do not like having to drag and drop my browser etc. I just right click the URL in Chrome and select (Play on My TV) a customized dropdown item, at which point my Player finds the TV, opens the URL, maximizes itself and plays the content
My application security from piracy depends upon fields in my databases. User has to activate the application, that writes Bought in my database. But the problem is if a new user installs my application and replaces all databases from some one who has bought key, the application also becomes active without buying key from me.
Is there any possibility that I could mark the databases to be recognized with the particular setup?
I've picked up some code from a colleague, and in one of his methods he has a boolean parameter: ByVal showProactiveChases As Boolean?. I had to look up the ? operator yesterday to see that it denotes a Nullable type. My question is, if I change it to: ByVal showProactiveChases As Nullable(Of Boolean), does the meaning remain the same? I think provided it doesn't change the meaning the second way is much more readable.
I had a need to mark a listview row if filenames were duplicates for n number of characters from the left. I wrote the following but it smacks of VB6.[code]...
I have a macro written in VB in Excel, which reads emails from Outlook. I would like to automatize this process, but everytime, when Excel wants to access the outlook, I have to give permition to do that, see http://apophis.wz.cz/permition.PNG (It's in czech, but you will see the point). Is there any way to give this permition for ever? Or for long time, such as 10 hours? (I can choose max. 10 minutes).
I have 9 textboxes in 1 form and couple of buttons to add unicode symbols inside the last active textbox when the button is pressed. So how do I find out which textbox was last active when the button was pressed.
new to VB and having some problems with my code.the story is that while marking items in comboBox1 need to pass values to 3 different comboBoxes so far I have made code that pass data only to one comboBox. [code]
The following code lets me insert an image into an Active X Image box using 'GetOpenFilename', however, if I push the Cancel button I get an error saying that the file cannot be found. Can anyone provide me with some advice on how to handle this error, the code is below?
Private Sub Image1_Click() Dim ImageOneLocation As String ImageOneLocation = Application.GetOpenFilename
I want to get the active control (control which has the focus or where the cursor is on) each time the cursor moves to another control or each time a control receives a focus.
In small project I am making , when I load the main for the list box is generated by data from xml ,well that done well , but I cant get the control active and I can getit to select item
Me activecontrol = listbox 1 ListBox1.SelectedItem = 0
I have got a project that i am currently creating that is a basic word processing application. There is the capability to have unlimited MDI child forms open however when you click on change font colour of something similar i only want it to do it in the currently active MDIChild. I have found the Me.activemdichild however i cant then access controls on that form.
I'm an old Access developer and know VBA quite well, but now I'm working at learning VB.net. I'm trying to find the equivilent of the following Access VBA code using VB.net:
Function EvalField() Dim x As Integer, ctl As Control Set ctl = Screen.ActiveControl x = Val(Mid(ctl.Name, 5)) Screen.ActiveForm.Controls("Formula" & x) = ctl ctl = Eval(ctl) UpdateTotal End Function
This code sets a control variable to the currently active control, then copies the text from that control into it's matching "Formula" field for reference by the user), then turns the string of math into the answer. For example, if the user enters 5 + 4, that will be copied to the Formula textbox, then it will be evaluated and the answer will replace the 5 + 4. And lastly, the UpdateTotal sub will execute which will add this answer to the existing Total field.
I have a tab control with two tabs. Both tabs have controls which are unique to them, but there is one control which I would like to always appear on whichever tab is currently active. I figure I just need to add some code to TabControl1_SelectedIndexChanged(). I tried
MyControl.Parent = TabControl1.TabPages( TabControl1.TabPages.IndexOf(TabControl1.SelectedTab)) MyControl.Parent.Update() ' is this necessary?
I'm using VB.NET within Visual Studio 2008.I have a ActiveX control on my form that contains a method that takes an Array. In VB6 I just passed in the array and it was populated OK. When I do the same in VB.NET, I get a result but the value of each index appears to be a pointer.Here is the C++ method code...
void CMyCtrl::GetRowInfo(const VARIANT FAR& vArray, short sNumRows) { // Declaretemp array to put the row list into short asRowList[24];
[code]....
Here is the VB code (same VB6 and VB.NET...
Dim maintRowList(0 To 23) As Integer AxMyCtrl.GetRowInfo(maintRowList, 24)
In VB6, the value of maintRowList(0) is in the range 0 to Windows screen height(its a pixel value)In VB.NET the value of maintRowList(0) is a value that looks like a pointer to me (e.g 285671429).In VB.NET, the type of the 1st parameter is Object. In VB6 it is a Variant. I've tried AxMyCtrl.GetRowInfo(maintRowList(0), 24) and got the same result. I think I need to get a pointer to either the array or the first element of the array but I can't see a way to do that. how I can pass an array to this type of C++ ActiveX method?BTW - I cannot change the ActiveX code so the solution must be within VB.NET.
i am making my final year project in vb.net for data entry i want to make the project more user friendly i use code to change the control focus by pressing 'Enter'(ASCII 13).. and clear the content of current control by pressing 'Esc'(ASCII 27)... in my project one form contains at-least 300 of controls say(t1,t2,t3,t4...)
so in the keypress event of t1 i have writen
if asc(e.keychar)=13 then t2.focus elseif asc(e.keychar)=27 then t1.text=nothing end if
the code works fine but produce an alert beep when i press ENTER to change the active control...
Is there any way to skip a the validating event of the active control when the close button of the form is clicked. It is very annoying when user wants to close the form, but due to the validate event of the active control, it asks for the valid input. The user is forced to give valid input to close the form. I have searched a lot for this on net but no any proper solution could be found.
how to specifically identify all the specific table cells that are selected in a webbrowser control. To be specific once I load a page into the webbrowser control and it is displayed I simply want to be able to click and drag with the mouse over multiple cells. Once I have selected the multiple cells I want to be able to do something to them such as adding an attribute. I can do this with a single cell. With the follwoing code:
I see tool like SN which generates private/public key pair for signing an assembly. And using AL tool we can assign a strong name to an assembly. And we have also Sign tool which is used for signing the assembly (probably for using with certificates exclusively?). What is the exact difference between the two?. Is it sign tool have to be used when working with certificates and can it we acheive it SN?. or are they totally different.?
I have an app published using ClickOnce. When an app is published that way, you get a temporary certificate which expires in a year. My year will be up in a couple months, and I am considering my options.One option, which a colleague is using, is to build a more sustained certificate using makecert.exe. By doing this, I can get a certificate of arbitrary length (or so I am told, as I haven't actually followed this route, yet). The problem with this route is that MS is pretty clear that makecert is for testing purposes.
I can also see that I could go to verisign or some such and buy a certificate, but that has a significant cost (well, I'm sure my employer wouldn't be too concerned about it, but it seems pretty high to me). The program has very narrow applicabiliity and narrow appeal (it has to do with counting fish). What I am wondering is whether there is sound reason to go with a certificate that is more than what makecert will create, and what that reason is? Additionally, I'm looking for information as to whether an internal CA, such as we have, which can make a certificate, will cause me any trouble if I use it to sign a ClickOnce app that won't be used entirely internal?
I'm converting a VB6 dll to VB.Net using Visual Studio 2008 Express. I want to use the same .dll to integrate with Excel via Excel-DNA, but also to be available via COM (I need to be able to call it from VBScript and VBA).
If I leave the assembly unsigned, I have access to all of the ExcelDNA functionality but no COM access.
If I sign the assembly with a strong name, then when I try to build the .dll I get the following error:
Unable to emit assembly: Referenced assembly 'ExcelDna.Integration' does not have a strong name.What are my options?
I've got a project which I would like to sign, however I've never done it before and I'm having a bit of trouble. The problem is that one of the dll files the project references is not signed. This results in an error, stating that the project assembly cannot be signed due to an unsigned referenced assembly. I'm not the author of the problematic unsigned assembly, so I can't sign it directly from VS (or at least I don't know how).
