I'm developing a Windows form. It contains textboxes, checkboxes and so on. When I move these controls (e.g. cut & paste from one frame to another in the same form), their names do not change (and it's good of course) but their function and event names are changed. Why it happens? How to avoid it? It causes me to move all functions from the old control to the new one. It's a lot of work and very annoying.

I'm getting familiar now with using the Dataset Designer and how it makes for quick and easy updates and query of tables. I use to use the OleDB commands and leave the Connection String as a Global Constant so I can easily change it if the server name changes, or if we have to re-direct the .NET to another instance of the database.
But now that I use the Dataset designer I'm concerned that I maintain flexibility and support in the long run. how the Dataset designer works and where it stores it's connection string info? And how difficult that would be to update. It looks like I modify the App.config file, but I'm unfamiliar with this.
What am I getting myself into? It looks like a standard XML file. Is that it?
I have hundreds of .pdfs that I downloaded that have names that are not helpful at first glance. Part of the download was a 'key' that lets me know which file belongs to which person (I have this in excel). I'd like to know if there is a vb script out there (or one I could get help writing) that would look in a folder and rename the files based on the accompanying spreadsheet.

It's just a small calculator project so it's no big deal, but after I had built the project, I wanted to change the project name and all the file names that had that string in it (and all internal references to that string). I had played with this before and knew that it was asking for trouble but I thought, "What the hell, I'll try it again." feeling a bit brash.
Well, everything works fine in debug mode, but there is this DOS window that pops up just before the main form does, and it doesn't go away for the entire debugging session. I think I see that window pop up on all other projects too (if the main form doesn't cover it up completely), but normally, it's only there for a split second.
I am trying some Uiculture change functionality. In that I need the name and text of controls in a form to change the culture. I got some Demo project and it is in C#. I tried to make the same functionality with the C#.net and Also using VB.net. But the below mentioned code returns control name with an underscore as prefix. But I don't want underscore. Code is actually written in Class library. It works perfectly in C#.
Code is written below

View 8 RepliesI am doing work for a client who has lost the source code for one of their VB.Net WinForms applications. The assembly they have is not obfuscated at all. I am trying to recover as much of the source as I can as C# source and have tried several tools for decompiling assemblies, including Reflector, ILSpy and JustDecompile (all the latest versions), but they all produce code with a huge number of errors in them. Because of the large number of errors in the generated code, I am going to ask about the specific errors (in different questions), get more directed answers and in this way try shed some light on why all the tools are having difficulty decompiling this assembly. This question pertains to the fact that the code generated by all these tools always have a large number of invalid member variables (fields) such as the following:
private short $STATIC$Report_Print$20211C1280B1$nHeight;
private ArrayList $STATIC$Report_Print$20211C1280B1$oColumnLefts;
private StaticLocalInitFlag $STATIC$Report_Print$20211C1280B1$oColumnLefts$Init;
why the generated code has these invalid member variables?

View 2 RepliesThis next program I am working on consists of 3 listbox's. The idea is to have the end user load names in the first and second list box. Then have a button's action when pressed combines the list in listbox1 with listbox2 then gives the output combination in listbox 3.
I also wanted to include some checkbox options such as adding a "_" or "." for every item.
Here is a thinking map of how I want it to work.

This is the code I have in one button and I have 2 listboxes that will be filled with the info it gets.This code should compare 1 avi file to one jpg file and see if they have the same name. If YES then it will add the avi path to one listbox. If they don't have the same name OR the .jpg doesn't exists it will add avi path to another listbox.. But currently it is adding the avi name to both listboxes.
View 6 RepliesI have a ComboBox with several names within it. The names are sourced from a database. Once the user has selected a name from the ComboBox, he must input the no. of hours from another ComboBox and then he is able save it to a .txt file through a streamwriter.

So, by using the example shown above, the file would be called bob.txt. Is this possible?There shouldn't be any save file dialog or anything, I want it to be automated and the name of the .txt file to be selected from the ComboBox.

I am creating files and then allowing the User to browse through the files via a ComboBox. I decided to name each file the current date. In order to create multiple reports each time the application is ran, each report needs a unique name.
The idea is that if they run a report once a day they'll have a unique report each day. But, then I realized that it is feasible that User could run a report more than once a day. So, I decided to create an integer and increment it each time the report has been ran. Then append the file name with that integer. So, report one of that day would show something like this:
12-22-2009_1 and so on.And this works just fine. But, if the user decides to close the app and then run the report later that day, the variable has been reset and no longer works as needed.I'm using a StreamWriter to create the file.
