GetFirstFile() return files is not correct

[ttagiio]

I use GetFirstFile()  to search the files in folder,most time is ok,but sometimes get error result ,for example , I search *30a*, the result is the file "YP09040882E.csv",search "30b",the result is"YP090408B0D.csv",it is strange, only occus in specific file name.

my code is :

 sprintf(ctemp,"\\*%s*",cYpText);  
 strcat (searchPath, ctemp);
        
 
 if (!GetFirstFile (searchPath, 1, 1, 0, 0, 0, 0, fileName))  {

........

}

You are saying this only happens sometimes - is this not reproducible every time? The "*30a*" search pattern should not result in a match to a file named "YP09040882E.csv". Try printing out the searchPath when this happens to make sure that variable has the expected value - may be searchPath is getting trashed for some reason. Also, if you program is multithreaded make sure your variables (ctemp, cYpText, searchPath, and fileName) are are not being used in multiple threads.

Hi Mohan,

thanks your quick reply.

this issue can reproducible. this issue is only found in some searching word, give you another sample,search the word "*34*",get result is "YP090409006""YP090408634"....,  you can see,"YP090409006" is wrong,see picture below show the code the variables :

I am a little bit afraid that I missed something very basic, but the help of GetFirstFile says, that the searchpath can contain the wildcard character *.

So including this wildcard should indeed return _any_ file, including YP09040882E...? No?

Hi ttagio,

Which version of CVI are you using? What is the path of the "filebrowsing" example? Also, can you attach the four files in your d:\1 folder, or give the names of these files?

Thanks,add my code and 4 files in 1.zip and run result in 1.jpg.
