I am trying to make sense of the return codes when I try to register and unregister COM objects - I can't seem to find a table that lists what the return codes mean.My application is able to register and unregister COM objects, for both .DLL and .EXE files.
- File.exe -RegServer // for executable files
- REGSVR32 File.dll // for dll files
I use CreateProcess to launch the com registration and GetExitCodeProcess to get the exit code when completed.But what do these return codes mean? Where can I find a Code<->Text translation?For example, when I unregister with -UnRegServer I usually get a return code of 28, with REGSVR32 I usually get 53...
I just added a reference to Excel interop in my VB.net project, but when I call new WorkBook it fails with an error:Retrieving the COM class factory for component with CLSID {00020819-0000-0000-C000-000000000046} failed due to the following error: 80040154.Do I need to regsvr32 a .dll or use dependency walker to find the problem? When I look in the registration database for that CLSID is points to Office 2010 which I have installed.[code]
I have been struggling to get vbscript working for last three days of relentless effort. I have windows 7 ultimate and upgraded from windows vista. searched the web for solutions and tried out all the options I think I have, but yet no luck.
I tried registering vbscript.dll and I get a succeeded message back. Everything seems to be fine. but, I just cannot run vbscript on my computer. It complains that "can't find script engine vbscript for script ....". I have a hunch that it is something to do with "microsfot security essentials (my virus protection software)" or with UAC.
I'm working up a system where I plan on using RealProxy objects to enable intercepting method calls against a set of objects, handling the call, and then returning appropriate results. This works just find for simple return types like strings or ints, but I can't seem to return objects from the RealProxy.Invoke method. Everything works. I get no errors, but the returned value is always NOTHING, instead of an object.
I've worked up the smallest sample code I could, and have included it below. Essentially, just call RPtest and single step through. The code creates a simple object, RPTestA, with a string field and an object valued field It then retrieves the string
I'm making a Visual Basic GUI application to display whether a number of my ports are open for people to know whether things like my website and my Minecraft server are open.My problem is I have absolutely no idea how to do this in Visual Basic.Basically, I'm asking for something which sends a signal to an IP with a specific port, if it is open then return true, if it's closed, return false. Similar to: http:[url]....

I am trying to translate some VB codes to C++. And I am not quite sure what this line does.
IIf (n& 1=1, 0.0005, -0.0005)
I know what IIf(logic, true_value, false_value) does, and I guess the & operator is supposed to concat two strings. But I am not sure what the intention of using "n & 1 =1".

This is for vb.net I've been working to develop a system which involves computation.What I've been trying to develop in my program is, I have a textbox where user will enter a numeric value,there is a button and a label below and in the first place the label should be set to zero. Everytime you enter a numeric value in the textbox and click the button it should add the value in the label and should save the value in the label so even if you exit the program whatever the last value displayed in the label should remain the same when run the program again,I believe it requires a database to save the value.Basically its like with payment system which saves the total amount of all payments made.
This is how should it works,say for example,if you will enter 1,2,3 it should save the sum value which is 6 in the label even if you close the program and when you run it again and enter another value it should add to the current value which is 6.
In C, Pascal, and C++ it is possible to use the FormatMessage function to retrieve a "friendly" error message that corresponds to a COM HRESULT error code. This question contains sample code that demonstrates the C++ approach. Of course it would be possible to build a managed C++ assembly to perform this function for C# and VB.NET code, but I'm wondering: is there a way to translate COM error codes using the .NET system libraries?
I need to be able to write data to a binary file. No problem - I have a test app I've knocked up that reads and writes to them fine, however the format uses C0 and C1 control codes, and I have no idea how to write them properly. The SOH, ENQ, DLE, NUL type of thing. I'd post some but they are non-printing. I know what they mean and what they do but have no idea how to write them.Basically we are writing our own system that generates test data files for import by another program. My files that I write have the correct number of fields and correct value and formats but because I can't get the tags to write they data is imported incorrectly. I've spent days reading up on it but can't find what I'm looking for.Not dealt with binary data files in VB before so this is all new.
I have a Windows form application written in VB of about 5000 lines of source code. For security reasons, I have changed all the names for variable, sub, and function to meaningless strings. For example strFileName to XBHDY. Apart from doing some test runs of the modified code, is there a reliable way to check that the two sets of codes are completely equivalent?

Writing codes for a school project I have to do. Basically I need to make a program that when you click a picture box it replaces the picture with an image in a second picture box on the same spot on the form. I am not sure how to do this. Right now I have the two pic boxes side by side and when I click one the other disappears as it should, but I can't get it to reappear so one can click between the two alternately.
I'm wondering if i can convert vb.net codes to python ?
I have this code"
[code]..............
i guess it's like:
[code].....................
so there any converter ? it would be so nice because i got source code for program in vb.net and as you know it's work on only Windows and i want to make it work in Linux so i need Vb to python converter ..
I was converting my VB6 codes to VB 2008. There is a section i use a third party application (Microsoft Excel) to print report. But now VB 2008 is not accepting one of my statement. the statment is shown below in bold letters.
I'm recently writing an app that is localizable and have several lauguage resources built within VS 2010 SP1. But now I came into a problem -- it seems that VS has modified one of the Designer.vb unregularly.The problem reveals like this. Whenever I want to change the main form's Language from Default into fr-CA (for eg, and with Localizable true), and after I save or run the project, then VS shows me with dozens of a same errors: 'Resources_ fr_ CA'is not a member of 'myApp'. The amount the this error I guess is depend on the number of controls on the form, but I'm not quite certain about that.Then I looked into the Designer file and found strange lines that were suddenly added by VS, they are somelike this two, not all these but commonly:[code]
The problem used to happened several times and it was passive before cos I can remove the lines one by one, using a text editor from outside. But now it is total nightmare, because, now whenever I set Language into French, the same problem MUST happen as saving the project. I can not debug or develop it with local language again, that is not any more a joke is it?
I am making a quick word processor, with the basics (alignment, cut, copy, paste, font size, font style etc.)I have four buttons for each of the font styles; Bold, Italic, Underline, and Strikeout.I have entered the following code, but my problem is, only one of the styles is used at a time, so if I use bold, then press italic, bold will be removed and italic will take its place. I want all four of the styles to be able to be used at once. [code]
I have a dataset that pulls information about topics. However, I need to filter the information so i only get the topics with certain Topic Codes (These topic codes are in the form of an array).
Me.TblTopicsTableAdapter.Fill(Me.MainDataSet.tblTopics)Right, let me try and explain better.
I have an array named COURSE_Topics. This array contains topic codes as string elements.Currently, my table adapter query looks like this:
SELECT [Topic Code], TopicName, NoOfCourses, Duration, StartDate, EndDate, [Level] FROM tblTopics At the end of that query i need to add a WHERE [Topic Code] = - then list of topic codes in the array.
After a stage i have found that there are lots of codes redundancy and reusement on my disk drive. And i have also noticed that for special operation i am using the similar algorithms again and again. So i thought that if there were a program that can find the functions from specific file types producing the output of the function list etc?
